Nonlinear active noise control of systems with a linear noisy secondary path

In this paper, an adaptive 3rd-order Volterra filtering is proposed for nonlinear active noise control (ANC) of systems with a cubically nonlinear primary acoustic path and a noisy secondary path, whereby a Gauss-Seidel fast affine projection (GS-FAP) algorithm is employed as an adaptive scheme. The simulation results demonstrate that the proposed nonlinear ANC approach yields stable ANC performance and faster convergence, compared with those of conventional ANC approaches in case of a noisy secondary path.
