凸组合μ-律比例自适应非线性回声消除方法
Convex Combination μ-law Proportional Adaptive Nonlinear Echo Cancellation Method
摘要
Abstract
In nonlinear adaptive echo cancellation,the nonlinear filter coefficients often have some redundancy,and only some coefficients can play an obvious role in signals modeling,that is,the nonlinear filter has sparse behavior.In order to improve the effect of eliminating nonlinear echo signal,a nonlinear echo cancellation method based on convex combination μ-law propor-tionate functional link adaptive filter is proposed.The output of a linear adaptive filter and a μ-law proportionate functional link adaptive filter is convexly combined,and the logarithm function in μ-law proportionate algorithm is replaced by a line segment function to reduce the computational burden.The experimental results show that the proposed method is better than other methods in nonlinear echo cancellation and has better echo cancellation effect and faster convergence rate.关键词
