Multi-channel acoustic echo cancellation(AEC) systems suffer from the non-uniqueness problem of the adaptive identification solution because of the correlation of the input signals.This paper investigates integrating a simplified blind signal separation (BSS) model into the stereophonic acoustic echo cancellation (SAEC).The integrated new structure translates the SAEC problem into two single-channel AEC problems so as to avoid the NUP and doesn't influence the audio quality. The simulation results improve the effectiveness of the new structure.
