考虑三阶分散情况下的高斯脉冲在光纤中的传输-Consider the case of third-order dispersion of the Gaussian pulse in optical fiber transmission

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
