中文说明：应用背景信号处理，盲信号分离、信号的特征提取，主要用于多个混合信号的盲分离。能消除混合信号之间的相关性，使得分离信号统计独立。关键技术 关键技术如下：通过采用Gram-Charlier多项式展开技术，估计信号的概率密度函数，然后可获得评价函数，可以实现超高斯和亚高斯混合信号的分离。
English Description：
Application backgroundSignal processing, blind signal separation, signal feature extraction, mainly used for blind separation of multiple mixed signals. Can eliminate the correlation between the mixed signal, so that the separation of signal statistics.Key TechnologyThe key techniques are as follows: the probability density function of the signal is estimated by using the Gram-Charlier polynomial expansion technique, and then the evaluation function can be obtained to realize the separation of the mixed signal of Gauss and Gauss.
