Most stereo teleconferencing systems involve acoustic echo canceller to remove undesired echoes. However, it is difficult for the stereo echo cancellers to converge to the true echo path since the cross-correlation between the stereo input signals is high. To solve the problem, we propose a new structure that is combined with Binaural Cue Coding (BCC). BCC is a method for multi-channel spatial rendering based on one down-mixed audio channel and side information. Based on the BCC, we propose a new single channel adaptive filter for the stereo echo cancellation, which takes the down-mixed monaural signal as the reference. Simulation results confirm that the convergence speed is increased and the misalignment problem is solved. In addition, the proposed structure has better tracking capability.
