摘　　要：为了减小水声通信系统中存在的由于多径传播效应引起的符号间干扰,在系统中使用了线性均衡器.本文首先介绍了几种LMS算法基本原理,利用Matlab仿真软件,给出了这几种算法在水声信道通信系统中的自适应均衡的仿真系统,并由这些算法对于均衡器的影响进行了比较,最后又对比较的结果进行了分析.To reduce inter-symbol interference which was due to multipath transmit effect in the water acoustic communication system, linear equalizer can be adopted in the system. This article introduces the basic principle of LMS algorithms , and makes use of Matlab simulation soft ware to provide the adaptive equalization system in the water acoustic system based on these algorithms, and compares the performance of these algorithms at last, and analyzes the result of comparison.
