Blind separation of convolved mixtures in the frequency domain

In this paper we employ information theoretic algorithms, previously used for separating instantaneous mixtures of sources, for separating convolved mixing in the frequency domain. It is observed that convolved mixing in the time domain corresponds to instantaneous mixing in the frequency domain. Such mixing can be inverted using simpler and more robust algorithms than the ones recently developed. Advantages of this approach are improved efficiency and better convergence features.
