Adaptive filter is a very powerful filter, and is an important part of statistical signal processing. It can automatically adjust the parameters according to the needs of a particular norm, eventually filtering to achieve the best results. Adaptive filtering algorithms can be divided into two kinds of linear algorithms and nonlinear algorithms. The most typical
