自适应时延估计的研究

In this paper a new adaptive time delay estimation method is presented. This method is based on least mean square (LMS) algorithm and correlation detection. The research model is introduced and the theory of algorithm is induced in section 2, which is the base of estimation. The LMS algorithm estimates the integral part of delay and the correlation detection gets the fractional part. In section 3 the structure figure of adaptive filter and the flow chart are given to help illustrating this new method. Computer simulations and experiments under different circumstances are made and some analysis or conclusions of the results are drawn in the last two sections.
