THE USE OF THE GAUSS-SEIDEL FAST AFFINE PROJECTION AND NLMS ALGORITHMS FOR OVERSAMPLED SUBBAND ACOUSTIC ECHO FILTERS

摘要

In this paper the use of the Gauss-Seidel Fast Affine Projection (GSFAP) and NLMS algorithms in a subband acoustic echo cancellation system is proposed. It is shown that the resulting structure can give better results that the full-band NLMS scheme in terms of both complexity and performance.
