Abstract
In this paper, we propose an approach to the blind separation-deconvolution problem, based on the mutual information criterion. Formulas for the quasi Newton algorithm are provided. More interesting results have been obtained in the pure deconvolution case. By a clever parameterization of the deconvoluting filter, the quasi Newton algorithm also become particularly simple. Simulation results showing the good performance of this algorithm are provided.
