Feasibility of blind signal separation using simultaneous perturbation method
Kenji Hamaguchi, K. Tsushio, Y. Maeda · 2003
Blind signal separation (BSS) is a technique in which original signals are extracted based only on observed signals. We propose a recursive method to obtain the separating matrix based on the mutual information via the simultaneous perturbation-optimization method. The feasibility of this method was confirmed by comparison with the natural gradient method.
