Synopsis  : 

Multi-user detection in CDMA systems results in tremendous increase in capacity when compared to that provided by conventional detectors. Some sub-optimal but easily implementable multiuser detectors for Single Input Single Output (SISO) systems have already been researched. One such detector is the Successive Interference Cancellation (SIC) multiuser detector.

 In this paper, we analyze the performance of a SIC multiuser detector with VBLAST to Multiple Input Multiple Output (MIMO) wireless systems using matlab tool box . The simulation results shows  the benefits of the SIC multiuser detector over the conventional detector for a few transmit-receive configurations. Further, the effect of thermal noise power on the performance of the SIC multiuser detector is simulated and the performance is analyzed.
