本文在讨论了海洋声信道时、空变特性的基础上，采用自适应滤波方法求信道响应函数。用所求得的响应函数进行信道匹配，取得明显效果。这里重要的是如何提高解自适应叠代方程的收敛速度。为此，本文除了采用步长因子自适应调节，频率域自适应滤波外，还提出合理设置权系数参量，使求解信道响应函数的速度提高。实验结果证明：在正确设置权系数之间时间关系的基础上，可以用有限数目的权个数，表示复杂的多途信道的响应函数。
In this paper, we discuss the space-time characteristics of oceanic acoustic channel, and adopt adaptive filtering method to obtain the channel response function. Obtained the obvious result by using the obtained response function for channel matching. What is important here is how to improve the convergence rate of the solution iterative equations. Therefore, in addition to the step-by-step adaptive adjustment and the frequency domain adaptive filtering, this paper also proposes to set the weight coefficient parameters reasonably so that the speed of solving the channel response function can be improved. Experimental results show that based on the time relationship between weight coefficients, a limited number of weights can be used to express the response functions of complex multi-lane channels.
