However, if the source signals have temporal structures, only the second-order statistics can work well.
如果源信号具有时序结构，仅使用二阶统计量信息就可以很好地分离源信号。
In this paper, the problem of blind identification and blind equalization of digital communication systems based on the second-order statistics (SOS) are addressed.
本文主要介绍了基于二阶统计量(SOS)的数字通信系统的盲辨识和盲均衡。
The method used to receive signals directly SVD decomposition in this paper, in order to avoid the original received signal second-order statistics, reducing the system's computational complexity.
文中采用的方法直接对接收信号进行SVD分解，避免了原文中求接收信号的二阶统计量，降低了系统的计算量。
