自适应CTLE 的研究

主要是三种。ZF ,LMS , RLS。

ZF 就是简单的逆运算。

LMS是自相关矩阵和互相关矩阵的求解,另外可能会需要用到伪逆。

RLS递归法暂时没有 写过。

按照matlab的介绍。

参考:https://ww2.mathworks.cn/help/comm/ug/equalization.html?#a1050772711b1

  • The LMS algorithm executes quickly but converges slowly, and its complexity grows linearly with the number of weights.

  • The RLS algorithm converges quickly, but its complexity grows with the square of the number of weights, roughly speaking. This algorithm can also be unstable when the number of weights is large.

我大致理解为如果多阶的ctle最好用lms,阶数少的话就是rls。

****有点想不明白的是,好像没有什么很多阶的ctle或者dfe。

所以,最终的理解为,信号完整性里面的ctle,dfe,既可以用rls 也可以用lms。
