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

使用蒙特卡罗方法模拟AWGN信道中QPSK的数字BER，并附加QPSK_AWGN.m脚本。 修改具有ZF接收机的系统中的瑞利平坦衰落信道的情况的代码。 在同一个图中绘制其数值和分析BER。(Use the Monte Carlo method to simulate the numerical BER of QPSK in AWGN channels, with the QPSK_AWGN.m scr ipt attached. Modify the code for the case o

or a generic communications link, this example focuses on transmit diversity in lieu of traditional receive diversity. Using the flat-fading Rayleigh channel, it illustrates the concept of Orthogonal Space-Time Block Coding, which is employable when
