AB  - It is well-known that the affine projection (AP) algorithm shows a good trade-off between computational effort and convergence speed. Nevertheless, the computational complexity of the AP algorithm increases with the projection order and low-computational versions, fast AP (FAP) algorithms, have been previously discussed. In this paper, a new FAP algorithm focused on the fast error vector calculation is proposed for active noise control. The new version uses the classical filtered-x structure instead of the commonly applied modified filtered-x. A comparative practical study of the different strategies has been also carried out and validates the use of the proposed method in ANC systems as an alternative to the previous versions since it provides lower computational cost.
