摘要
对变步长的(LMS)自适应算法进行了讨论,本文提出了一种新的变步长LMS自适应滤波算法,并用计算机进行了仿真,结果表明该算法在误差接近于零时步长具有缓慢的变化的特性,并且在低信噪比的环境下有更好的抗噪性能,滤波效果更好。
This paper discusses the variable step size least mean square （ LMS ） adaptive filtering algorithm. A new LMS adaptive filtering algorithm with variable step size is proposed. The simulation results show that when algorithm＇s error approach to zero, it has the characteristics of a slow change and better anti-noise property in low signal noise ratio environment, also the results of filtering is better.
