基于盲源分离的水声信道盲均衡处理方法

提出了一种基于盲源分离的水声信道盲均衡处理方法，通过对接收信号过采样构成源信号，采用了基于信道最大化原理（Infomax）的在线分离算法进行了水声信道的盲均衡，并研究了时变水声信道条件下算法的均衡情况，仿真实验结果表明：该处理方法对多径水声信道具有较好的均衡效果，同时不受最小相位的条件限制。

Blind source separation based underwater acoustic channel blind equalization

An underwater acoustic channel blind equalization method via the blind source separation theory is presented. Constructing source signal by oversampling of the received signal, an on-line separation algorithm based on infomax principle is employed to equalize the underwater acoustic channel. Convengence results in both time-invariant and time-variant channel are studied. Simulation experiment shows that without the limit of minimum phase, the proposed algorithm gains promising results in multipath underwater acoustic channel.
