CDMA base station system

Abstract

Abstract A CDMA base station system, in which the main system structure comprises a central control module, channel module, analog module, modulated data transmission bus, inter-module transceiving bus, sampling bus, common control bus and monitor, wherein said three modules, four buses and monitor are used to not only enable the downlink channel data transmission between the base station and certain mobile terminal, the uplink channel data transmission between certain mobile terminals and the base station and bi-way subscriber data transmission between the base station and base station control center via E1 interface, but also provide the functions of the sending/receiving of analog signals, the modulation/demodulation of base frequency signal and the downlink channel and uplink channel processing of data processing. The monitor can be applied to achieve the setup, test and fault detection. The point-to-point test functions for base station control center and certain mobile terminals as well as that for certain mobile terminals and base station control center can be simulated. Central control module proceeds on-line monitoring of channel modules plugged in the slots and abnormal conditions via the common control bus and inter-module transceiving bus.
