MIMO QPSK系统迫零检测算法，可以运行-ZF algorithm in MIMO system with QPSK modulation

This setup illustrates the principle of coherent detection and digital signal processing (DSP) for a coherent 112Gb/s QPSK signal. The system performance is limited by noise (added in front of the receiver), chromatic dispersion and PMD (taking place
