Abstract :
A multi-channel acoustic echo (MCAE) suppression model via blind signal separation (BSS) is proposed. It avoids the inherent non-uniqueness problem in MCAE cancellation due to strongly cross-correlated acoustic echo-source signals. On the contrary, it makes full use of the cross-correlativity to remove echoes from a microphone input. Experimental results confirm its effectiveness.
