A short duration zero mean white Gaussian noise is injected into the system using an active loudspeaker and the GLD algorithm is employed to recursively estimate the secondary path. The performance of the proposed scheme is compared with that obtained by filtered-x least mean square (FxLMS) algorithm based ANC system and Eriksson's method in terms of ensemble mean square error and convergence rate. The new scheme is shown to effectively model the secondary path even without prior knowledge of its order.falseActive noise control | Generalized levinson durbin algorithm | Online secondary path modeling | White noise injectionConference Paper552-555201446900726cpConference Proceeding2
