Starting from the characteristics of high-speed digital signal processor, the principle of adaptive filter and the main application fields, the basic theory of adaptive filter is introduced, and the basic principle, algorithm and design method of adaptive filter are described in detail. In this paper, two basic adaptive algorithms, namely the minimum mean square error (LMS) algorithm and recursive least squares (RLS) algorithm are introduced and analyzed in detail, and the advantages and disadvantages of the two algorithms are compared in detail. Finally, the adaptive filter is implemented by DSP. The experimental results show that the adaptive filter has better filtering effect.
