| Abstract(in English) | In an active noise control (ANC) system with online secondary-path modeling based on auxiliary white noise injection, the residual noise power may be reduced by scaling the auxiliary noise using a function of the residual noise signal. In this paper, dynamics of a filtered-X LMS (FXLMS) based narrowband ANC system with online secondary-path modeling using an auxiliary white noise scaled by one-sample-delayed residual noise signal is analyzed. Difference equations governing the dynamics of the system are derived and discussed. Extensive simulations are conducted to illustrated the effectiveness of auxiliary noise scaling and the validity of the analytical results. |
