    变步长自适应滤波算法,对VS—LMS算法进行了改进,建立了步长因子μ与误差信号e(n)之间另一种新的非线性函数关系.理论分析和计算机仿真结果表明,该关系不仅具有原有算法收敛速度快的优点,而且在低信噪比环境下比原有算法具有更好的抗噪声性能.(The variable step size adaptive filtering algorithm is discussed, and the VS-LMS algorithm is improved. A new nonlinear function relation between the step size factor μ and the error signal e (n) is established. Theoretical analysis and computer simulation results show that the proposed algorithm not only has the advantages of high convergence speed of the original algorithm, but also has better anti- noise performance in the low SNR environment than the original algorithm.)
