基于LMS算法的陷波滤波器的研究

daptive signal processing of modern signal and information processing an important part of the adaptive filter has its own ability to adjust parameters to achieve the best noise cancellation. This paper describes the basic theory of adaptive signal processing and adaptive filtering of the basic algorithm, using adaptive filter design techniques, using mean square error (LMS) algorithm, designed to eliminate a useful signal in an additive sine-wave interference function of adaptive notch filter. Study of the MATLAB software, designed and carried out simulation experiments using MATLAB, combined with simulation results, the performance of filter design and adaptive algorithm performance is analyzed
