摘要
论文提出了一种变步长解相关的LMS算法,解决了传统LMS算法固定步长的缺点,并根据输入信号的相关性原理对迭代更新方向向量进行了改进,提高了迭代速度,并使用MATLAB仿真对提出的新的算法的有效性进行了验证。
In this paper,a variable step-size and uncorrelated algorithm is discussed in order to overcome the shortcoming of conventional LMS algorithm for its fixed step size.The convergence speed is also improved by using the theory of correlation.The new algorithm 's efficiency has been approved by simulation using MATLAB.
