[Forward path]
The LTE FWD MIMO0, MIMO1 and modem combined signals sent from the optic module of MHU is first divided into MIMO0, MIMO1 and modem signals at RFMUX in RU, then the FWD RF signals are amplified and filtered at the RFBS0 and RFBS1 module. The modem signal is conveyed to CPU of NMS controller through FSK modem. LTE signal is reduced by the Crest Factor passing through the CFR FPGA digital board inside RFBS0 and RFBS1. This technology enables reduction of PAPR for LTE signal increasing HPA efficiency. A higher efficiency HPA allows using a smaller enclosure with lower power consumption while decreasing OPEX for the service provider. The LTE RF signals from the RFBS modules is linearly amplified up to high power level on HPA, passed through the Front-End Filter Unit, and finally transmitted through a coverage antenna.
[Reverse Path]
LTE Rx signals incoming from coverage antennas are first passed by the Front-End Filter Unit, amplified by a low noise and high gain amplifier, filtered in RRBS and RRBS1, and combined with modem signal and 10MHz at combiner(RRCOM). The combined signal is then transmitted to MHU through the optic module. Kisan Telecom Confidential Proprietary 11 / 30 4.1.5.
