Abstract :
The multiuser detection of space coded, multi input multi output (MIMO), code division multiple access (CDMA) signals in the downlink direction is investigated. The main interference in the system results from the time mismatch of the receving antennas. The robust successive interference cancellation (RSIC) detector is used to detect the signals received from multi receving antennas having time mismatches. The performance of RSIC in nonideal situations such as incomplete channel state information, correlated antennas, impulsive noise is investigated. The results show that RSIC performs adequately even under these adverse conditions.
