title = "A clipping-based adaptive filtering approach for stereophonic acoustic echo cancellation",
abstract = "The use of partial-updating algorithm for reducing interchannel coherence in stereophonic acoustic echo cancellation has been proposed recently. In this work, we show that this algorithm suffers from the lack of robustness against source positions in the transmission room. To address this, we present an insight into this problem and propose a center clipping algorithm that improves the joint optimization between reducing interchannel coherence and increasing energies of selected taps for different source positions. Simulation results using both colored and speech inputs verify the robustness of the proposed algorithm against source positions.",
