A multichannel filtered-x affine projection algorithm for active noise control (ANC) systems based on dichotomous coordinate descent (DCD) iterations is proposed. It is shown that it has better convergence properties, lower complexity, and improved robustness to inaccuracies of the plant model than other previously published algorithms for ANC systems.
