A METHOD AND APPARATUS FOR BLIND SOURCE SEPARATION
摘要
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.
