ABSTRACT:
The invention discloses to a signal processing method for user equipment in a CDMA mobile communication system. The signal processing method is a combination of time diversity and joint detection in order to raise diversity gain of a receiver. The method comprises: sample a received signal on time domain, estimate spatial channel impulse response value, obtain matrixes, constitute a system matrix, perform joint detection algorithm and obtain an estimated value of original sending data. When the method is used in a mobile user equipment, the uplink and downlink performance unmatched problem can be solved, using same frequency multiplexing can be reached and the joint detection algorithm is a simpler one. The method also can be used in a base station.
