基于LMS算法的自适应组合滤波器(中文3500字,英文2600字)
摘要：提出了一种自适应组合滤波器。它由并行LMS的自适应FIR滤波器和一个具有更好的选择性的算法组成。作为正在研究中的滤波器算法比较标准，我们采取偏差和加权系数之间的方差比。仿真结果证实了提出的自适应滤波器的优点。

Combined Adaptive Filter with LMS-Based Algorithms
Abstract: A combined adaptive filter is proposed. It consists of parallel LMS-based adaptive FIR filters and an algorithm for choosing the better among them. As a criterion for comparison of the considered algorithms in the proposed filter, we take the ratio between bias and variance of the weighting coefficients.
Simulations results confirm the advantages of the proposed adaptive filter.
Keywords: Adaptive filter, LMS algorithm, Combined algorithm,Bias and variance trade-off
