Stability Analysis of the Algorithms for Blind Source Separation Based on Cross-Cumulants
Yan Liu · Systems engineering and electronics · 2003
NguyeThi and Jutten have proposed the algorithms for separating the signals of convolutive mixtures based on 4thorder cumulants. In this paper, the stability of the algorithms is studied. It is shown that not all the algorithms can converge to the proper separation matrix and only one can converge to the right solution.
