Abstract
In this paper, we propose an approach for combined acoustic echo and noise cancellation based on the Gauss-Seidel pseudo affine project algorithm (GS-PAP). It includes a simple residual echo cancellation scheme and a double-talk detector using a two-path model. Simulation results indicate that the proposed GS-PAP is stable, fast, convergent and has good tracking abilities, which are attractive for acoustic echo cancellation.
