摘　　要：Conventionally, multi-channel acoustic echo cancellation （AEC） achieves the goal by estimating the impulse responses of the local room. However, generally, conventional AEC methods have no unique solutions. Due to the strong correlation of the input signals, conventional methods are with many disadvantages. To overcome this problem, a new framework is proposed in this paper based on SIMO （single input multiple output） blind deconvolution. Under the new framework, we achieve the goal by identifying the impulse responses of distant room and avoiding the disadvantages of the conventional methods.

关 键 词：SIMO blind deconvolution multi-channel acoustic echo cancellation impulse response.
