Feedback Active Noise Control using Linear Prediction Filter for Colored Wide-band Background Noise Environment

Abstract

In this paper, we propose a new Feedback Active Noise Control (FB-ANC) system to improve the suppression performance for narrow-band noise buried in colored wideband background noise. The proposed system adopts a linear prediction filter to the input signal in order to separate narrowband noise and wide-band noise. The simulation result shows the proposed method can perform robust noise suppression.
