摘　　要：本文讨论了弱光反馈对相干光差分相移键控系统误码率的影响。指出:在适当的反馈条件下,弱光反馈可以改善系统的误码率性能。The effects of weak optical feedback (WOF) on the bit error rate (BER) of coherent optical differential phase shift key-controll (DPSK) systems are presented. The results indicate that the BER properties of the systems can be improved by WOF under suitable feedback conditions.
