分析多径瑞利分布下，BPSK调制信号的误比特率和信号比的关系-The relationship between the SNR and BER in multiple rayleigh for BPSK signal.

In this simulation, a 2 x 2 MIMO system with BPSK modulation is used. Then, the algorithm of V-BLAST is implemented. After that, weight vector is produced using ZF, MMSE and ML detectors. Finally, the BER performance is plotted. A flat fading Rayleig
