MIMO (multi-input multi-output) systems can achieve high data capacity and high data rate in the third generation (3G) or beyond-3G mobile communication systems. To effectively improve the performance of MIMO systems, new detection schemes which can mitigate mutual interferences from multiple transmit antennas, are highly required. In this paper, we consider a posteriori probability (APP) type detection schemes for the MIMO systems, and compare with other sub-optimal detection schemes based on zero forcing (ZF) and minimum mean square error (MMSE) - ordered successive interference cancellation (OSIC). Simulation results show that the APP outperforms ZF-OSIC and MMSE-OSIC, while the performance discrepancy becomes smaller as the number of receive antennas increases.
