LMS：最小均方（LMS）算法是一种自适应滤波器，用于通过查找与产生误差信号的最小均方（期望信号和实际信号之间的差值）相关的滤波器系数来模拟期望滤波器
English Description：
LMS: the least mean square (LMS) algorithm is an adaptive filter used to simulate the desired filter by finding the filter coefficient related to the least mean square (the difference between the expected signal and the actual signal) that generates the error signal
