Frequency-domain weighted FxLMS algorithm for feedback active noise control

Abstract

In this paper, we propose the frequency-domain weighted FxLMS algorithm for feedback active noise control. This algorithm aims to resolve the slow convergence issue of the conventional FxLMS algorithms by integrating a frequency-weighted method. This method dynamically adjusts weights based on the amplitude-frequency characteristics of narrowband noise, thereby improving tracking performance for time-varying narrowband noise. Through simulation experiments, we reveal that the FD-WFxNLMS algorithm achieves fast convergence, outperforming the conventional algorithms in feedback ANC systems.
