MULTICHANNEL SIGNAL SEPARATION - METHODS AND ANALYSIS

The problem of multichannel signal separation has attracted considerab le interest in recent literature, A variety of methods and criteria ha ve been proposed to solve the problem based on statistical independenc e between the source signals. Most of these criteria involve the compu tation of high-order statistics of the observed signals. In this paper , we present a unified framework for many of these criteria and analyz e their statistical variance.
