A robust active noise control algorithm without identifying secondary path

It has been shown that active noise control (ANC) can be done without identifying the secondary path. However, the method given in based on the cumulative error power is ad-hoc, slow, and not general. In this paper, we propose a new algorithm that is more robust to the ANC-without-identifying-secondary-path problem based on a more general secondary-path decomposition and step-size adaptation.
