-1900 Service Manual Application Information General Introduction The EMII-1900 functions digital cellular module worked in CDMA (Code Division Multiple Access) mode. CDMA type digital mode applies DSSS (Direct Sequence Spread Spectrum) mode which is used in military. This feature enables the phone to keep communication from being crossed and use one frequency channel by multiple users in the same specific area, resulting that it increases the capacity 10 times more compared with that in the analog mode currently used. Soft/Softer Handoff, Hard Handoff, and Dynamic RF power Control technologies are combined into this phone to reduce the call being interrupted in a middle of talking over phone. CDMA digital cellular network consists of MSC (Mobile Switching Controller), BTS (Base station Transmission System), and MS (Mobile Station). Communication between MS and BTS is designed to meet the specification of IS -95A (Common Air Interface). MS meets the specifications of the below :

- IS-95A ( Common Air Interface ) : Protocol between MS and BTS

- IS-96A ( Vocoder ) : Voice signal coding

- IS-98 : Basic MS functions

- IS-126 : Voice loopback

- IS-99 : Short Message Service, Async Data Service, and G3 Fax Service EMII-1900 is digital mode is designed to be operated in full duplex. Office), BSC (Base Station EMII-1900 V1.0 AnyDATA.NET Proprietary Use Subject to Restrictions EMII-1900 CHAPTER 1 . System Introduction 1. System Introduction 1.1 CDMA Abstract The cellular system has a channel hand -off function that is used for collecting the information on the locations and movements of radio mobile telephones from the cell site by automatically controlling several cell site through the setup of data transmission routes and thus, enabling one switching system to carry out the automatic remote adjustment. This is to maintain continuously the call state through the automatic location confirmation and automatic radio channel conversion when the busy subscriber moves from the service area of one cell site to that of another by using automatic location confirmation and automatic radio channel conversion functions. The call state can be maintained continuously by the information exchange between switching systems when the busy subscriber moves from one cellular system area to the other cellular system area. In the cellular system, the cell site is a smal l-sized low output type and utilizes a frequency allocation system that considers mutual interference, in an effort to enable the re -use of corresponding frequency from a cell site separated more than a certain distance. The analog cellular systems are cla ssified further into an AMPS system, E -AMPS System, NMT system, ETACS system, and JTACS system depending on technologies used. Unlike the time division multiple access (TDMA) or frequency division multiple access (FDMA) used in the band limited environment, the Code Division Multiple Access(CDMA) system which is one of digital cellular systems is a multi technology under the interference limited environment. It can process more number of subscribers compared to other systems

(TDMA system has the pro cessing capacity three times greater than the existing FDMA system whereas CDMA system, about 12~15 times of that of the existing system). CDMA system can be explained as follows: TDMA or SDMA can be used to enable each person to talk alternately or provide a separate room for each person when two persons desire to talk with each other at the same time, whereas FDMA can be used to enable one person to talk in soprano, whereas the other in bass (one of the two talkers can carry out synchronization for heari ng in case there is a bandpass filter function in the area of the hearer). Another method available is to make two persons to sing in different languages at the same time, space, and frequency when wishing to let the audience hear the singing without being confused. This is the characteristics of CDMA. On the other hand, when employing the CDMA technology, each signal has a different pseudo-random binary sequence used to spread the spectrum of carrier. A great number of CDMA signals share the same frequen cy spectrum. In the perspective of frequency area or time area, several CDMA signals are overlapped. Among these types of signals, only desired signal energy is selected and received through the use of pre -determined binary sequence; desired signals can be separated and then, received with the correlator used for recovering the spectrum into its original state. At this time, the spectrums of other signals that have different codes are not recovered into its original state and instead, processed as noise and appears as the self -interference of the system.

-1900 Service Manual Application Information Interface Description EMII 2. Features and Advantages of CDMA Module 2.1 Various Types of Diversities In the CDMA broadband modulation(1.25MHz band), three types of diversities (time, frequency, and space) are used to reduce serious fading problems generated from radio channels in order to obtain high-quality calls. Time diversity can be obtained through the use of code interleaving and error correction code whereas frequency diversity can be obtained by spreading signal energy to more wider frequency band. The fading related to normal frequency can affect the normal 200~300kHz among signal bands and accordingly, serious affect can be avoided. Moreover, space diversity (also called path diversity) can be realized with the following three types of methods. First, it can be obtained by the duplication of cell site receive antenna. Second, it can be obtained through the use of multi-signal processing device that receives a transmit signal having each different transmission delay time and then, combines them. Third, it can be obtained through the multiple cell site connection (Soft Handoff) that connects the mobile station and more than two cell sites at the same time. 2.2 Power Control The CDMA system utilizes the forward (from a base station to mobile station s) and backward (from the mobile station to the base station) power control in order to increase the call processing capacity and obtain high-quality calls. In case the originating signals of mobile stations are received by the cell site in the minimum call quality level (signal to interference) through the use of transmit power control on all the mobile stations, the system capacity can be maximized. If the signal of mobile station is received too strong, the performance of tha t mobile station is improved. However, because of this, the interference on other mobile stations using the same channel is increased and accordingly, the call quality of other subscribers is reduced unless the maximum accommodation capacity is reduced. In the CDMA system, forward power control, backward open loop power control, and closed loop power control methods are used. The forward power control is carried out in the cell site to reduce the transmit power on mobile stations less affected by the multi-path fading and shadow phenomenon and the interference of other cell sites when the mobile station is not engaged in the call or is relatively nearer to the corresponding cell site. This is also used to provide additional power to mobile stations having high call error rates, located in bad reception areas or far away from the cell site. The backward open loop power control is carried out in a corresponding mobile station; the mobile station measures power received from the cell site and then, reversely inc reases/decreases transmit power in order to compensate channel changes caused by the forward link path loss and terrain characteristics in relation to the mobile station in the cell site. By doing so, all the mobile office transmit signals in the cells are received by the cell site in the same strength. Moreover, the backward closed loop power control used by the mobile station to control power with the commands issued out by the cell site. The cell site receives the signal of each corresponding mobile stat threshold value and then, issues out power increase/decrease commands to the corresponding mobile station every 1.25 msec

(800 times per second). By doing so, the gain tolerance and the different radio propagation loss on the forward/backward link are complemented. ion and compares this with the pre

-1900 Service Manual Application Information 2.3 Voice Encoder and Variable Data Speed The bi -directional voice service having variable data speed provides voice communication which employs voice encoder algorithm having power variable data rat e between the mobile telephone cell site and mobile station. On the other hand, the transmit voice encoder performs voice sampling and then, creates encoded voice packets to be sent out to the receive voice encoder, whereas the receive voice encoder demodulates the received voice packets into voice samples. One of the two voice encoders described in the above is selected for use depending on inputted automatic conditions and message/data; both of them utilize four -stage frames of 9600, 4800, 2400, and 1200 bits per second. In addition, this type of variable voice encoder utilizes adaptive threshold values when selecting required data rate. It is adjusted in accordance with the size of background noise and the data rate is increased to high rate only when the voice of caller is inputted. Therefore, background noise is suppressed and high -quality voice transmission is possible under the environment experiencing serious noise. In addition, in case the caller does not talk, data transmission rate is reduced so that the transmission is carried out in low energy. This will reduce the interference on other CDMA signals and as a result, improve system performance

(capacity, increased by about two times). 2.4 Protecting Call Confidentiality CDMA signals have the function of effectively protecting call confidentiality by spreading and interleaving call information in broad bandwidth. This makes the unauthorized use of crosstalk, search receiver, and radio very hard substantially. Also included is the encryption func tion on various authentication and calls specified in IS confidentiality. 2.5 Soft Handoff During the soft hand, the cell site already in the busy state and the cell site to be engaged in the call later participate i n the call conversion. The call conversion is carried out through the original call connection cell site, both cell sites, and then, new cell site. This method can minimize call disconnection and prevent the user from detecting the hand-off. 2.6 Frequency Re-Use and Sector Segmentation Unlike the existing analog cellular system, the CDMA system can reuse the same frequency at the adjacent cell and accordingly, there is no need to prepare a separate frequency plan. Total interference generated on mobile station signals received from the cell site is the sum of interference generated from other mobile stations in the same cell site and interference generated from the mobile station of adjacent cell site. That is, each mobile station signal generates interf erence in relation to the signals of all the other mobile signals. Total interference from all the adjacent cell sites is the ratio of interference from all the cell sites versus total interference from other mobile stations in the same cell site (about 65%). In the case of directional cell site, one cell normally uses a 120 sector antenna in order to divide the sector into three. In this case, each antenna is used only for 1/3 of mobile stations in the cell site

-1900 Service Manual Application Information and accordingly, interference is reduced by 1/3 on the average and the capacity that can be supported by the entire system is increased by three times. 2.7 Soft Capacity The subscriber capacity of CDMA system is flexible depending on the relation between the number of users and service classes. For example, the system operator can increase the number of channels available for use during the busy hour despite the drop in call quality. This type of function requires 40% of normal call channels in the standby mode during the handoff support, in an effort to avoid call disconnection resulting from the lack of channels. In addition, in the CDMA system, services and service charges are classified further into different classes so that more transmit power can be allocated to high class service users for easier call set-up; they can also be given higher priority of using hand -off function than the general users.

-1900 Service Manual Application Information Interface Description EMII 3. Structure and Functions of CDMA Module The mobile station of CDMA system is made up of a radio frequency part and logic/control (digital) part. The mobile station antenna is connected with the transmitter/receiver via a duplexer filter so that it can carry out the transmit/receive function at the same time. The transmit frequency is the 60MHz band of 1851. 25 ~ 1908.75MHz, whereas the recei ve frequency is the 60MHz band of 1931.25 ~ 1988.75MHz. The transmit/receive frequency is separated by 80MHz. The RF signal from the antenna is converted into intermediate frequency(IF) band by the frequency synthesizer and frequency down converter and then, passes the bandpass SAW filter having the 1.25MHz band. IF output signals that have been filtered from spurious signal are converted into digital signals via an analog-to-digital converters(ADC) and then, sent out respectively to 5 correlators in each C DMA de-modulator. Of these, one is called a searcher whereas the remaining 4 are called data receiver(finger). Digitalized IF signals include a great number of call signals that have been sent out by the adjacent cells. These signals are detected with pseu do-noise sequence (PN Sequence). Signal to interference ratio (C/I) on signals that match the desired PN sequence are increased through this type of correlation detection process. Then, other signals obtain processing gain by not increasing the ratio. The channel from the cell site most adjacently located is demodulated in order to obtain the sequence of encoded data symbols. During the operation with one cell site, the searcher searches out multi-paths in accordance with terrain and building reflections. On three data receivers, the most powerful four paths are allocated for the parallel tracing and receiving. Fading resistance can be improved a great deal by obtaining the diversity combined output for de -modulation. Moreover, the sear cher can be used to determine the most powerful path from the cell sites even during the soft handoff during the two cell sites. Moreover, four data receivers are allocated in order to carry out the de-modulation of these paths. Data output that has been demodulated change the data string in the combined data row as in the case of original signals(deinterleaving), and then, are de

-modulated by the forward error correction decoder which uses the Viterbi algorithm. On the other hand, mobile station user information sent out from the mobile station to the cell site pass through the digital voice encoder via a mike. Then, they are encoded and forward errors are corrected through the use of convolution encoder. Then, the order of code rows is changed in accordance with a certain regulation in order to remove any errors in the interleaver. Symbols made through the above process are spread after being loaded onto PN carrier waves. At this time, PN sequence is selected by each address designated in each call. Signals that have been code spread as above are digital modulated (QPSK) and then, power controlled at the automatic gain control amplifier (AGC Amp). Then, they are converted into RF band by the frequency synthesizer synchronizing these signals to proper output frequencies. Transmit signals obtained pass through the duplexer filter and then, are sent out to the cell site via the antenna. EMII-1900 V1.0 AnyDATA.NET Proprietary Use Subject to Restrictions

-1900 Service Manual Application Information Interface Description EMII CHAPTER 3 . Circuit Description 1. Overview RFT3100 receives modulated digital signals from the MSM of the digital circuit and then, changes them into analog signals by the digital/analog converter (DAC, D/A Converter) in order to create baseban d signals. Created baseband signals are changed into IF signals by RFT3100 and then, fed into the Mixer after going through AGC. IF signals that have been fed are mixed with the signals of VCO and changed into the RF signals and then, they are amplified at the Power AMP. Finally, they are sent out to the cell site via the antenna after going through the isolator and duplexer. 2. RF Transmit / Receive Part 2.1 CDMA Transmit End 8 bit I and Q transmit signals are inputted into 2 DACs (DIGITAL -TO-ANALOG CONVERTER) from the output terminal I_DATA, I_DATA \, Q_DATA, Q_DATA \ of MSM through the input terminals I_DATA, I_DATA\, Q_DATA, Q_DATA \ of RFT3100. Transmit signal input speed is two times of TXCLK+, TXCLK- which are two transmit/receive reference frequency. Among transmit signals being inputted, signals are inputted into I signal DAC when the transmit clock is in the rise edge, whereas signals are inputted into Q Signal DAC during the drop edge. I and Q transmit signals are compensated and outputted at MSM in order to compensate the 1/2 clock time difference generated between reference clocks. In the signals coming out from the output terminal of DAC, there are spurious frequency ingredients resulting from DAC output transition edge and parasite ingredie nts, transmit clock frequencies and harmonics which are unwanted signals. Accordingly, spurious ingredients are removed by passing the signals through LPF of passband 6.30KHz. Unlike the receive end, the transmit end LPF requires no OFFSET adjustment. Anal og baseband signals that have passed the CDMA LPF are mixed with I and Q signals of frequency 130.38 MHz (260.76 MHz created in the RFT3100 internal VCO are divided by half into frequency 130.38MHz having the phase difference of 90 degrees) in two mixers. The mixed signals are added again and converted into IF frequency 130.38 MHz 630 KHz

(CDMA Spread Power Density Modulated Signals) and then, outputted. 2.2. Tx IF/Baseband Processors, RFT3100 (U102) The RFT3100 includes digital -to-analog converters(DA C) for converting digital baseband to analog baseband, low -pass filters, a mixer for up amplifier. The RFT3100 has an IF mixer for upconverting analog baseband to IF, a programmable PLL for generating Tx IF frequency, single sideband upconversion from IF to RF, two cellular and two PCS driver amplifiers. The RFT3100 will operate over the follow Tx frequency ranges :

Transmit End Bandpass Filter (F102, F103) Transmit signals that have been converted from IF signals into RF signals after passing through the RFT3100(U102) are inputted into the Power Amp

(F101) in order to filter out noise signal through RFT3100(U102). This is carried out in order to create power level inputted to the Power AMP via RF BPF (F101). IL of a RF BPF is 2dB as a maximum, whereas the ripple in the passing band is 2dB(maximum). The degree of the suppression of transmit signals on receive band is at least 20dB or greater. The maximum power that can be inputted is about 25dBm. 2.4. Power Amplifier (U102) The power amplifier U102 that can be used in the CDMA a nd FM mode has linear amplification capability, whereas in the FM mode, it has a high efficiency. For higher efficiency, it is made up of one MMIC (Monolithic Microwave Integrated Circuit) for which RF input terminal and internal interface circuit are inte grated onto one IC after going through the AlGaAs/GaAs HBT (heterojunction bipolar transistor) process. The module of power amplifier is made up of an output end interface circuit including this MMIC. The maximum power that can be inputted through the inpu t terminal is +17dBm and conversion gain is about 28dB. RF transmit signals that have been amplified through the power amplifier are sent to the duplexer and then, sent out to the cell site through the antenna in order to prevent any damages on circuits, that may be generated by output signals reflected from the duplexer and re -inputted to the power amplifier output end. 2.5. Description of Frequency Synthesizer Circuit 2.5.1 Voltage Control Temperature Compensation Crystal Oscillator(TXC201, VCTCXO) The temperature range that can be compensated by TCX201 which is the reference frequency generator of mobile terminal is -30 ~ +80 degrees. TCX201 receives frequency tuning signals called TRK_LO_ADJ from MSM as 0.5V~2.5V DC via R and C filters in order t o generate the reference frequency of 19.68MHz and input it into the frequency synthesizer of UHF band. Frequency stability depending on temperature is 2.0 ppm. EMII-1900 V1.0 AnyDATA.NET Proprietary Use Subject to Restrictions

-1900 Service Manual Application Information Interface Description EMII 2.5.2 UHF Band Frequency Synthesizer (U202) Reference frequency that can be inputted to U202 is 3MHz~40MHz. It is the dual mode frequency synthesizer (PLL) that can synthesize the frequencies of RF band 50MHz~1200MHz and IF band 20MHz~300MHz. U202 that receives the reference frequency of 19.68MHz from TCX201 creates 30kHz comparison frequency with the use of internal program and then, changes the frequency of 1750MHz band inputted from U204 which is the voltage adjustment crystal oscillator into the comparison frequency of 30kHz at the prescaler in U202. Then, two signal differences are calculated from the internal phase comparator. The calculated difference is inputted to DC for adjusting the frequency of U174 through U172 No.2 PIN and external loop filter in order to generate UHF signals. In addition, outputs of other PIN17 are inputted into BBA after going through the VRACTOR diode and tank circuit so that the outputs of BBA internal receive end VCO are adjusted to 170.76MHz. 2.5.3 Voltage Control Crystal Oscillator (U204) U204 that generates the LO frequency (1750MHz) of mobile terminal receives the output voltage of PLL U202 and then, generates the frequency of 1720MHz at 0.7V and the frequency of 1780MHz at 2.7V. The control voltage sensitivity is 23MHz/v and the output level is 1dBm(maximum). Since LO frequency signal is very important for the sensitivity of mobile terminal, it must has good spurious characteristics. U204 is -70dBc(maximum).

[Figure 3-1] Block Diagram of Digital/Voice Processing Part 3.3.1 MSM Part MSM5105, which is U 401, is the core element o f CDMA system terminal that includes ARM7TDMI microprocessor core. It is made up of a CPU, encoder, interleaver, deinterleaver, Viterbi decoder, MOD/DEM, and vocoder. MSM5105, when operated in the CDMA mode, utilizes CHIPX8 (9.8304MHz) as the reference clo ck that is received from IFR3000, and uses TCXO (19.68MHz) that is received from TCX201. CPU controls the terminal operation. Digital voice data that have been inputted are voice-encoded and variable -rated. Then, they are convolutionally encoded so that er ror detection and correction are possible. Coded symbols are interleaved in order to cope with multi -path fading. Each data channel is scrambled by the long code PN sequence of the user in order to ensure the confidentiality of calls. Moreover, binary quadrature codes are used based on Walsh functions in order to discern each channel. Data created thus are 4-phase modulated by one pair of Pilot PN code and they are used to create I and Q data. When received, I and Q data are demodulated into symbols by the demodulator and then, de -interleaved in reverse to the case of transmission. Then, the errors of data received from Viterbi decoder are detected and corrected. They are voice decoded at the vocoder in order to output digital voice data.
