The Multiple-Input Multiple-Output (MIMO) system has emerged in recent years as one of the most significant technical breakthroughs in modern communications since it has the potential to increasing the spectrum efficiency and transmission capacity. Minimum Mean-Square Error (MMSE) or Zero-Forcing (ZF) detection algorithm can be applied in MIMO detection. But the linear detectors suffer significant performance loss in fading channel. The scheme of Maximum Likelihood (ML) detection offers the best decoding performance. However, the computational complexity increases exponentially with the number of transmit antennas and modulation order.
