摘要

本文提出一种带有旋转因子的归一化多路回波消除算法NLMS-RF

并对算法进行了分析和几何解释.进一步地

我们将所提算法扩展成一种带有旋转因子的多路回波消除仿射算法APA-RF.NLMS-RF算法的计算量远小于Sankaran(1999)所提的多路回波消除算法

而APA-RF的计算量与Benesty(1996)所提出的算法的计算量相当.在收敛精度和速度上

NLMS-RF和APA-RF分别较Sankaran(1999) 和Benesty(1996)所提算法有较大的改善.仿真结果表明所提算法的有效性.

Abstract

A Normal Least Mean Square adaptive filtering algorithm with rotating factor (NLMS-RF) is proposed and its performance and geometry property is analyzed in this paper.Furthermore

it is extend to a multi-channel Affine Projection Algorithm with rotating factor (APA-RF) for stereophonic echo cancellation.The computational complexity of the NLMS-RF is much lower than that of Sankaran's (1999)

and the computational complexity of the APA-RF is as much as that of Benesty's (1996).As compared with Benesty's (1996) and Sankaran's (1999)

the NLMS-RF and APA-RF is of faster convergence and more accuracy respectively.The simulation in MATLAB indicates its efficiency.
