摘　　要：对100 Gbit/s偏振复用-正交相移键控(DP-QPSK)系统中使用数字信号处理(DSP)技术同时实现对光信号色散补偿、偏振解复用和相位估计的方案进行了讨论,并采用OptiSystem 9.0软件对该方案的效果进行了验证,仿真结果表明该技术方案实现简单且可靠性高,对优化相干光检测硬件有参考意义。A scheme to achieve optical signal dispersion compensation,polarized solution reuse and phase estimation at the same time in 100 Gbit / s DP-QPSK System by using coherent reception technology is discussed. The effect of this scheme is verified with OptiSystem9. 0,and the simulation results indicate that this scheme is implemented simply and has high reliability,and it also has reference significance for the optimization of coherent optical detection hardware.
