Abstract :
In this paper, a new proportionate affine projection sign algorithm using the μ -law proportionality idea is proposed. It has an efficient implementation because it uses a fast recursive filtering procedure. Simulation results indicate that the proposed algorithm has slightly better performance than a competing algorithm in a network echo cancellation system in impulsive environments and adaptive feedback cancellation for hearing aids systems.
