摘　　要：自适应技术是目前光通信研究热点之一的接收机均衡技术的重要组成部分。文章在简要介绍光接收机中常用的均衡处理技术的基础上,总结了应用较多的LMS等多种自适应均衡算法的基本形式,并对目前有关算法在光通信中应用的研究结果及多种的算法改进进行了总结和分析,同时对与其紧密相关的反馈监测信号的选取等问题进行了对比分析。Adaptive optimization techniques are an essential part of the receiver equalization technologies, which is one of hot topics in optical communications now. This paper summarizes the widely used adaptive optimization algorithms, such as the LMS algorithm, after briefly introducing the commonly used equalization schemes in optical receivers. We also give a summary and analysis of the current research results on the application of these schemes in optical communications as well as introducing the variations and improvements of these methods, A comparison of other issues, such as the choice of the feedback monitoring signals is also discussed.
