中文说明：2*2的天线阵列，发射信号经过瑞利信道到达接收端的误码率（BER）曲线的分析，其中包括迫零检测均衡（ZF），最大比值合并（MRC），以及最小均方误差准则检测算法（MMSE）等，并且对其进行了理论和仿真的比较。程序都能运行。
English Description：
2 * 2 antenna array. The BER curve of the transmitted signal arriving at the receiving end through Rayleigh channel is analyzed, including zero forcing detection equalization (ZF), maximum ratio combining (MRC), minimum mean square error criterion detection algorithm (MMSE), and so on. The theoretical and simulation results are compared. The program can run.
