摘　　要：在对自适应滤波器相关理论研究的基础上,重点研究了LMS自适应滤波算法,给出了不同信噪比条件下,LMS算法的Matlab仿真实现的滤波结果,通过分析仿真结果可以看出,在一定信噪比范围内,LMS算法在未知信号与噪声统计特性的条件下可以达到较好的滤波效果。On the basis of research on adaptive filter theory,LMS adaptive filter algorithm is especially studied,and filter results of LMS algorithm are given using Matlab in different SNR. It can be concluded through analyzing simulation results that LMS algorithm has better filter results without signal and noise statistical characteristics in some certain SNR.
