摘要

我们提出并演示了一种新的非决策辅助修正最小均方(NDA-MLMS)算法，用于联合盲均衡和载波恢复。在14Gbaud的4-QAM系统中，使用线宽为500khz的激光，传输100km后，误码率达到10-3,OSNR损失小于1.9dB。

Non-decision aid modified least mean square algorithm for joint blind equalization and carrier recovery in optical coherent receiver

We propose and demonstrate a new Non-Decision Aid Modified Least Mean Square (NDA-MLMS) algorithm for joint blind equalization and carrier recovery. The bit error rate (BER) of 10-3 is achieved with less than 1.9dB OSNR penalty for 14Gbaud 4-QAM system after 100km transmission and 500 KHz linewidth laser.
