Abstract

A proportionate affine projection like (PAPL-I) adaptive filtering algorithm is proposed that incorporates the proportionate feature to affine projection like (APL-I) algorithm. Simulation results show that the proposed PAPL-I algorithm provides improved steady state performance than the APL-I and affine projection algorithms (APA) in case of an acoustic echo cancellation application with a very sparse echo path. In addition, the PAPL-I algorithm also offers improved performance over the APL-I algorithm for adaptive feedback cancellation for hearing aids systems.
