摘要

本文提出了一种时变归一化LMS (TVS-NLMS)算法来适应回波抵消结构。该算法在不显著增加计算量和降低归一化LMS算法收敛速度的前提下，减少了双话过程中的失真。仿真结果证实了所提方案的理想特性。

A time varying step size normalized LMS echo canceler algorithm

This paper proposes a time varying normalized LMS (TVS-NLMS) algorithm for adapting an echo canceler structure. Proposed algorithm reduces distortion during double-talk, without increasing the computational cost nor decreasing the convergence rate of the normalized LMS algorithm significantly. Simulation results confirm the desirable features of the proposed schema.<>
