Abstract
The Direction of Arrival estimation algorithm ESPRIT is capable of estimating the angles of arrival of N narrowband source signals using M>N anechoic sensor mixtures from a uniform linear array (ULA). Using a similar parameter estimation step, the DUET Blind Source Separation algorithm can demix N>2 speech signals using M=2 anechoic mixtures of the signals. The present invention demixes N>M speech signals using M>=2 anechoic mixtures.
