processor, a transmission unit, a power unit and a heat exchanger. The
working principle of the system is as follows:
In the downlink direction, the ZXG10 OB06 (V1.0) receives data from BSC,
including voice and signaling data. Here, the signaling data are sent to the
control, operation & maintenance unit for processing. The voice data are
first sent to the base band processor for processing such as rate
conversion, encryption and interleaving, sent to the RF unit to be
modulated to high-frequency signals, and then finally transmitted through
the antenna feeder processor.
In the uplink direction, the antenna feeder processor receives the RF
signals from the MS, and sends them to the RF unit to convert them into
digital signals. Then, the signals are sent to the baseband processor for
rate conversion, decryption and de-interleaving. Finally, after being
converted to the code pattern suitable for long-distance transmission, the
signals are sent to the BSC through the Abis interface.
