A computationally efficient version of the affine projection (AP) algorithm avoiding matrix inversions is presented and developed for multichannel active noise control (ANC) systems. A comparative study of the classical multichannel filtered-x LMS (MFXLMS), the multichannel filtered-x affine projection (MFXAP) and its computationally efficient version… (More)
