摘要: 提出了一種基于盲源分離的水聲信道訊均衡處理方法,通過對接收信號過采樣構(gòu)成源信號,采用了基于信息最大化原理(Infomax)在線分離算法進行了水聲信道的盲均衡,并研究了時變水聲信道條件下算法的均衡情況,仿真實驗結(jié)果表明,該處理方法對多徑水聲信道具有較好的均衡效果,同時不受最小相位的條件限制。

Abstract: 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 infoniax 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. -
