The Variable Step-Size Gauss-Seidel Pseudo Affine Projection Algorithm

Abstract

In this paper, a new pseudo affine projection (AP) algorithm based on Gauss-Seidel (GS) iterations is proposed for acoustic echo cancellation (AEC). It is shown that the algorithm is robust against near-end signal variations (including double-talk). Keywords—pseudo affine projection algorithm, acoustic echo cancellation, double-talk.
