Figure 1 gives the illustration of the common wireless communication system structure. Wireless communication
system is required to have one or more antenna 101.1∼101.K. K is the number of antenna and K is no less than 1. Since
antenna need to undertake the double function of transmitting and receiving wireless signals, thus duplexer 102.1∼102.K.
is generally required. As to the wireless signal received, it needs to be transformed into base band digital signal by the
process of signal enlargement, spectrum removal, band pass filtration, automatic gain control, discrete time sampling,
and analog-to-digital conversion, etc conducted by the receive radio frequency processing module 103.1∼103.K. The
base band signal of multi-antenna is then through data exchange module 106 to be provided to the subsequent base
band process. Usually, data exchange module 106 is a module used for processing the send-and-receive of back board
data on a back board and veneer of a rack. In the commercial system, generally there exist equipments such as radio
frequency remote module and repeater station, etc. All these equipments stretch radio frequency process part beyond
several hundreds or even more than ten kilometers by electric cable, optical fiber or microwave, while the base band
process part is centralize conducted in computer room. At this time, data exchange module 106 contains more complicated
equipments like electric cable, optical fiber conversion transceiver module, microwave transceiver module, etc.
