Abstract
In this paper, we construct a unified blind signal separation model for network and acoustic echo cancellation and propose using a convolutive blind signal separation method based on higher-order statistics to perform joint speech signal separation and echo cancellation. The advantage of this approach is that it works well in the presence of double talk which seriously affects the performance of conventional echo cancellers. The performance is verified by simulation results
