| Abstract: | 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. |
