A multi-resolution filtered-x LMS algorithm based on discrete wavelet transform for active noise control
A new active control algorithm based on discrete wavelet transform (DWT) is proposed, which update the adaptive filter coefficients in frequency domain. The proposed active control algorithm, so-called DWT-FFT-FXLMS algorithm is verified and compared with TD-FXLMS and FD-FXLMS algorithms. Simulation results suggest that the DWT-FFT-FXLMS algorithm is effective for both stationary and non-stationary noise cancellation.
