相干DSP系统仿真程序，并且具有光纤信道仿真特性-coherent system DSP simulation program, and also include the fiber channel simulation program

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
