盲信号提取算法研究与分析

Research and Analysis on Blind Signal Extraction Algorithm

盲信号提取主要研究如何把源信号逐个从观察信号中提取出来。以矩阵理论为基础,推证了在病态条件下逐个从观察信号中提取出主要源信号的可行性,并对给出的BSE学习算法,在病态条件下进行分析仿真。

Blind signal extraction researches mainly on how to extract the source signal sequentially from the mixed signals.First,on the base of matrix theory,this paper deduces the feasibility of blind signal extraction in the ill conditions.Then a leaning algorithm on blind signal extraction is proposed.The result of analysis and the computer simulation result show that the proposed algorithm can extract the desired source signal in the ill conditions.
