Study of Switched Step-size Based Filtered-x NLMS Algorithm for Active Noise Cancellation
arXiv:2601.16382v1 Announce Type: new Abstract: While the filtered-x normalized least mean square (FxNLMS) algorithm is widely applied due to its simple structure and easy implementation for active noise control system, it faces two critical limitations: the fixed step-size causes a trade-off between convergence rate and steady-state residual error, and its performance deteriorates significantly in impulsive noise environments. To address the step-size constraint issue, we propose the switched mbox{step-size} FxNLMS (SSS-FxNLMS) algorithm. Specifically, we derive the mbox{mean-square} deviation (MSD) […]
