Paper Abstract

The source recovery step in underdetermined blind source separation is probed in this paper. DUET is famous method in underdetermined blind source separation. However, it requires the sources are approximately disjoint. To obtain good results in sources recovery, an improved DUET algorithm is proposed for two mixtures. The algorithm utilizes DUET after the rotation of the mixing matrix and mixtures. Several speech signals experiments demonstrate its performance and practical.
