Semi-Blind Source Separation for Nonlinear Acoustic Echo Cancellation

1 code implementation • 25 Oct 2020 • Guoliang Cheng, Lele Liao, Hongsheng Chen, Jing Lu

Unlike the commonly utilized adaptive algorithm, the proposed SBSS is based on the independence between the near-end signal and the reference signals, and is less sensitive to the mismatch of nonlinearity between the numerical and actual models.

Nonlinear Residual Echo Suppression Based on Multi-stream Conv-TasNet

1 code implementation • 15 May 2020 • Hongsheng Chen, Teng Xiang, Kai Chen, Jing Lu

Acoustic echo cannot be entirely removed by linear adaptive filters due to the nonlinear relationship between the echo and far-end signal.
