Abstract
In this paper, we present an adaptive filtering algorithm for multichannel active noise cancellation (ANC) system in frequency domain. This approach rests upon the frequency domain block filtered-x LMS algorithm and NLMS algorithm, utilization of which facilitates variable step size control for multichannel ANC. Computational complexity for the proposed algorithm is evaluated and the performance of the proposed algorithm is validated through computer simulations for multichannel ANC.
