Abstract
In this paper, we simulate and evaluate the performance of MIMO systems adopting MMSE-OSUC receiver algorithm under Rayleigh fading channel environment. In the simulation, BPSK, QPSK, 16QAM, and 64QAM modulation is used with frame length of 100 symbols. First, the concept of MIMO is introduced by the analytical basis of the channel capacity of MIMO system. From the performance analysis results, the channel capacity is identified by the function of channel and it is affected by the channel characteristic. Next, based on this approach, the algorithm for performance evaluation over MIMO channel was analyzed. From the performance analysis results, it is found that MMSE-OSUC receiver algorithm generally outperform conventional ZF-OUSC receiver algorithm in performance but the performance difference between the two algorithms is reduced as modulation scheme with larger constellation point is used.
