Cumulant-Based Blind Separation of Convolutive Mixtures

This paper focuses on the blind source separation of convolutive mixtures based on high order cumulants. It is proved that the zero-forcing of pairwise cross-cumulants of the outputs of separation system is a sufficient criterion for the separation of convolutive mixtures. New algorithm is developed based on this criterion. Simulation results are presented to support the validity of the algorithm.
