摘　　要：自适应滤波器作为一种现代滤波器,在通信领域有着广泛的应用.阐述了LMS自适应滤波器的相关原理及其在通信系统去噪中的应用,并用MATLAB对选取不同步长因子的自适应滤波器的去噪结果进行了相应的仿真,仿真结果直观地体现了自适应滤波器的去噪性能,以及选取不同步长因子对信号收敛性能的影响.As a classic filter, adaptive filter has many applications in the field of communications. This articlefocuses on the relevant principles of LMS-based adaptive filter and its application in communication system by us-ing MATLAB to simulate denoising with different step-size factor. The results show that the denoising effect and theconvergence of adaptive filter are directly influenced by the step-size factor.
