摘　　要：针对基于LMS算法的自适应时延估计算法收敛速度慢的缺点,推导出一种基于RLS算法的自适应时延估计算法,并分析了基于RLS算法的自适应滤波器的均值性能。经仿真证明该算法的收敛速度有了一定提高,并且其时延估计的跟踪性能得到了改善。Due to the slow convergence speed of adaptive time delay estimation algorithm based on LMS algorithm, an adaptive time delay estimation algorithm based on RKS algorithm is proposed, and mean behavior of the adaptive filter based on RLS algorithm is analyzed. Compared with the former al- gorithm, the convergence speed of this algorithm is improved definitely, and this algorithm has a better tracking performance of time delay estimation.
