Acoustic Echo Canceller with Blind Source Separation

Acoustic echo cancellation (AEC) aim to suppress the echo picked up by the micro phone in a hand free communication system. There are so many techniques which are used for removing of acoustic echo from original speech signal. We propose to apply a independent component analysis (ICA) technique for separation of near end signal for echoes. Proposed method can be regarded as a optimal coupling of linear echo canceller, multi channel source separation and non linear echo canceller under a proposed blind source separation technique.
