摘要：

This paper presents an improved FxLMS algorithm to accomplish the active noise control (ANC) task. In many situations, there may exist some unwanted acoustic noise whose frequency falls into in a certain band. In order to cancel such noise in the given frequency band, we introduce bandpass filters into the original FxLMS structure. Because the introduced bandpass filters can only allow the noise in that given band to pass, the cancellation performance can be significantly improved for such noise. Simulation were done to confirm the effectiveness of our ANC method.
