A multi-resolution filtered-x LMS algorithm based on discrete wavelet transform for active noise control
TL;DR: A new active control algorithm based on discrete wavelet transform (DWT) for both stationary and non-stationary noise control that has greatly reduced complexity and a better convergence performance compared to a time domain filtered-x least mean square (TD-FXLMS) algorithm.

Z. H. Xu,C.-M. Lee,Z. Qiu +2 more
TL;DR: Two kinds of anti-audio interference active noise control (ANC) algorithms are proposed based on a conventional filtered-X least mean squares virtual microphone (FXLMS-VM) algorithm that show better convergence accuracy in terms of the adaptive filter coefficients and better audio signal performance than the conventional algorithm.
