1. 该程序进行了简单的LMS信道估计，没有加入与MMSE等其他信道估计算法的比较；

2. 程序中循环前缀的设置，作者称是25％的CP，但是从矩阵的构造并不能看出这一点

并且CP为Zero-CP，需要加入与真正复制了数据样值的循环CP系统进行性能对比

3. 仿真条件为系统处于理想同步情况下。

-1. The program had a simple LMS channel estimation, not joined with the MMSE channel estimation algorithm and other comparative　2. Program cyclic prefix settings, the author claimed to be 25　CP, but from the matrix structure can not be seen This and the CP as a Zero-CP, need to be added to copy the data samples with the true value of the cycle of CP system performance comparison　3. simulation conditions for the system is in an ideal synchronous case.
