Abstract |
Contrast-based separation of sources has a number of advantages. Among others, they are optimal in presence of noise. In this work, we propose a new contrast by considering a so-called reference signal that allows not only obtaining the optimal numerical algorithm but also yields better performance in terms of variance of the estimated mixing filter. This contrast needs source kurtosis to have the same sign. Thus, it's appropriate to multichannel blind deconvolution. |
