Multichannel signal separation: methods and analysis
Daniel M. Yellin, Ehud Weinstein · IEEE Transactions on Signal Processing · 1996
The problem of multichannel signal separation has attracted considerable interest in recent literature. A variety of methods and criteria have been proposed to solve the problem based on statistical independence between the source signals. Most of these criteria involve the computation of high-order statistics of the observed signals. We present a unified framework for many of these criteria and analyze their statistical variance.
