这是光纤通信DPSK误码率检测的源程序，实现对误码率的检测-This is the optical fiber communication DPSK BER detection of the source, to achieve BER testing

这是光纤通信信号生成的MATLAB源程序，在发送端信号生成后由调制器调制之后经过光纤传输，是光纤通信的基础-This is the optical fiber communication signal generation MATLAB source, is the basis of the entire optical fiber communication
