Abstract:
1. A space domain filter detecting method in a multi-antenna wireless communication system, which treats interference in time domain and interference in space domain differently, the method comprising: Step 1: performing matched combination for a plurality of received signals in the time domain and the space domain to obtain combined signals; Step 2: taking the combined signals as observation values of signals to be detected, and performing filtering in the space domain on the basis of corresponding criterions to obtain filtered signals; Step 3: removing estimated values of interference signals from the filtered signals to obtain a detection output, and sending the detection output to a decider unit in an encoding system without error control to obtain a hard-decision output of symbols, or sending the detection output to a soft demodulator in an error control encoding system to obtain soft information of a plurality of transmitted bits, and then sending the hard-decision output of the symbols or the soft information of the plurality of transmitted bits to a decoder.
