LMS

1.This point out that in order to improve the LMS algorithm performance, the gradient are optimally estimated, or the error signal are nonlinearity processed,these methods are equipollent.

最速下降法的梯度优化估值差信号非线性处理，是改善LMS算法性能的等同措施。

2.A new variable step-size LMS adaptive filtering algorithm is presented, which makes use of the intercorrelation function of the relative output error signal to control the new variable step-size.

针上述问题，提出了种新的变LMS自适应滤波算法，它采用相的差互相关函数来控制新。
