Criterion for Blind Signals Separation Based on Correlation Function被引量：1
《Chinese Journal of Aeronautics》2003年第3期162-168,共7页宋友 柳重堪 李其汉 
Blind separation of source signals usually relies either on the condition of statistically independence or involving their higher-order cumulants. The model of two channels signal separation is considered. A criterion...
