基于MATLAB与DSP的自适应滤波器设计与实现
Design and implementation of self-adapting filter based on MATLAB and DSP
摘要
Abstract
The filtering is a technology to filter the waveform of some certain frequencies. In digital signal processing , the filtering is mainly used to filter noise and interference signals. Because of the uncertainty of noise and interference signal , using the digital filter of fixed filter coefficients can′t achieve the best effect. However, the self-adapting filter can change its parameters and structure with the change of the environments which can accommodate to the changing noise and interference signals so as to realize the ideal filter. After studying the Least Mean Square algorithm (here referred as LMS), as well as analyzing the structure and principle the of the self-adapting filter, the paper designed a self-adapting filter of FIR structure. In the end, it gave the MATLAB simulation results, and used DSP to test the performance of the new design.关键词
