最小均方算法，借助于最速下降算法发展起来的，通过维纳滤波所求维纳解，已知输入信号与期望信号的先验统计信息，以及再对输入信号的自相关矩阵进行求逆运算的情况下才能得以确定，计算复杂程度低，收敛性好(Least mean square algorithm, with the help of the steepest descent algorithm is developed, using wiener filtering for wiener solution of known prior statistical information input signal and the desired signal, and then the input signal under the condition of inversion of the autocorrelation matrix can be determined, low computing complexity and good convergence)
