| 摘 要： | 水声信道环境恶劣，尤其是多径效应常会造成水声通信系统同步位置发生偏移，对均衡算法造成严重影响。从提高均衡算法稳健性的角度出发。在稳定性较高的归一化常数模算法基础上，借助早迟积分比相原理完成对采样位置的跟踪，并结合判决正方形方法提出一种归一化修正常模盲均衡算法。仿真结果表明．这种基于判决正方形的归一化修正常模盲均衡算法具有更好的收敛能力与稳定性，具有较强的抗干扰能力，能保证水声通信高效运行。

| Abstract: | The environments of underwater acoustic channel is very abominable.Especially the multipath effect,which will cause synchronous position offset of underwater acoustic communication system,had serious influence to equalization algorithm.Aiming to improve the robustness of equalization algorithm,this article adopted the theory of early-late integration phase comparison to track the sampling position on the basis of the more steady normalized constant modulus algorithm and brought forward one new normalized mo... |
