Absolute Mean Error Based Adaptive Step Size Affine Projection Algorithm for Adaptive Filtering Systems
Keywords:
Adaptive filter, adaptive step size, affine projection algorithm.Abstract
This paper presents a new method for adaptive
step size for Affine Projection Algorithm (APA). The proposed
algorithm is based on an absolute mean of estimation current
and prior error vector. It is called Absolute Mean Error
Adaptive Step Size Affine Projection Algorithm (AMASSAPA).
The main goal of this algorithm is performance enhancement of
adaptive colored filtering system in terms of fast convergence
time. The proposed adaptive step size method begins the
learning process with high learning rate value ( µ MAX ) and
then , it decays in an exponential profile to its minimum value
(µMIN ) .The proposed algorithm is tested with a colored input
signal and the result shows that it has fast convergence time
than traditional APA.
