qpsk信号瑞利信道的仿真程序还有搞死的有ber(qpsk signal Rayleigh channel simulation program has also Gaosi ber)

Simulink model for QBSK

本程序模拟了一个2DPSK发送和接受的完整过程，差分编码采用模2加的方式得到，本次实验采用的是相移键控的方法得到发送信号，2DPSK信号最常用的解调方法有两种，本次实验采用的是极性比较法，先通过2PSK相干解调器，再经过码（反）变换器得到基带信号。 (This program simulates a 2DPSK sending and receiving complete process, differential coding is completed by modulo-2 addition； the experiment using the phase shift keying method to send signals.this experiment is the polarity comparison method,firstly go through the 2PSK coherent demodulator and then pass through code (trans) converter to obtain a baseband signal.)
