摘要

组合方法为提高自适应滤波性能提供了灵活、通用的解决方案。本文研究了两个时变LMS自适应滤波器仿射组合的均方性能。这种组合的目的是获得收敛速度快、均方误差小的电视LMS自适应滤波器。b[1]中提出的两种实际方案用于这种情况。仿真结果表明，这两种方案产生的总体MSE小于任何一种滤波器的MSE。而且这种组合优于两个LMS自适应滤波器的组合。

An affine combination of two time varying LMS adaptive filters

Combination approaches provide flexible and versatile solution to improve adaptive filter performance. In this paper, mean square performance of an affine combination of two time varying (TV) LMS adaptive filters is studied. The purpose of this combination is to obtain TV LMS adaptive filter with fast convergence and small mean square error (MSE).Two practical schemes proposed in [1] are used for this case. Simulation results indicate that these schemes yield overall MSE that is less than the MSE of either filter. Moreover this combination is better than combination of two LMS adaptive filters.
