Adapted deflation approach for referenced contrast optimization in blind MIMO convolutive source separation

Abstract

The paper deals with the problem of the blind source separation after a MIMO convolutive mixture. The source separation is done with successive extractions of one source signal that is a deflation approach. The extraction stage is performed using a MISO equalizer and based on a third order tensor decomposition. Computer simulations illustrate the good behavior and the usefulness of our algorithm in comparison with algorithms based on fourth order tensor. © Springer-Verlag Berlin Heidelberg 2009.
