ICASSP 1997, 22nd IEEE international conference on acoustics, speech, and signal processing, April 21-24 1997, Munich, Germany
Contrast-based separation of sources have a number of advantages. Among others, they are optimal (in a precise sense) in presence of noise of unknown statistics. Here a new contrast is proposed that allows not only to obtain the optimal solution analytically, but also yields better performances in terms of variance of the estimated mixing matrix. This contrast needs source kurtosis to have the same sign, and is thus appropriate to multichannel blind equalization in communications.
