摘　　要：讨论了LMS方法对瞬态信号估计的困难,提出用反向LMS自适应滤波算法进行瞬态信号的时延估计。设计了两种反向LMS自适应算法,用爆炸波信号仿真分析了时间延迟估计的性能,通过比较表明该算法的有效性。The problems of time - delay estimation based on LMS adaptive algorithm are discussed. Reverse LMS adaptive algorithm for time - delay estimation of transient signal is presented. Two reverse LMS adaptive algorithms are designed. Time - delay estimation of explosion wave is analyzed by using simulation method. Comparison results show that the algorithm proposed in this paper is effective.
