Discussion of Simple Algorithms and Methods to Separate Non-stationary Signals.
Ali Mansour, Noboru Ohnishi · 2000
In the last decade, many researchers haveinvestigated the blind separation of sources and many algorithms have been proposed to solve this problem for the case of an instantaneous mixture (memoryless mixture) [1]. In general, high-order statistics (i.e., fourth order) are used. However, it has been shown that algorithms and criteria can be simplified by adding special assumptions [2].
