Multichannel Fast Affine Projection algorithm with Gradient Adaptive Step-Size and fast computation of adaptive filter output signal

Abstract

The paper presents a computational procedure of a multichannel Fast Affine Projection algorithm. The procedure also includes Sliding Window linear prediction, Gradient Adaptive Step-Size and fast computation of adaptive filter output signal. An example of the algorithm application in a combined Feed-Forward and Feed Backward Active Noise Control system, which can be viewed as a two-channel adaptive filter, and simulation results are discussed.
