基于正交小波变换的瞬变步长LMS自适应滤波算法
A adaptive LMS algorithm with transient step based on orthogonal wavelet transform
摘要
Abstract
Based on orthogonal wavelet transform, a modified adaptive algorithm(WTSPLMS )using smooth pseudo LMS(SPLMS)with transient step is presented in this paper. At the same time, it has taken advantage of the character of orthogonal wavelet with locality in time-frequency domains. Besides having advantages of SPLMS, it has faster beginning convergence rate, lower misadjustment of weight, and better robustness aganist noise and disturbance. The theoretical analysis is confirmed by the computer simulation results.关键词
