Summary:
Filtered-x algorithm is widely used for an active noise control (ANC). However, it has a possibility of making ANC unstable due to the modeling error of secondary path. Therefore, this paper introduces a bias free structure into the estimation of the inverse transfer function of the secondary path. The proposed structure takes advantage of the delay of the primary path.
