- Abstract
- In this paper, we propose a multi-channel active noise control (ANC) system with online acoustic feedback path modeling (OFPM) based on a variable step-size least-mean-square (VSS-LMS) algorithm and noise power scheduling. In particular, an acoustic feedback signal may degrade the performance of an ANC system and an additive random noise is applied to model the acoustic feedback path. However, the additive noise signal contributes as the residual noise to the system output. The proposed approach reduces such residual noise by confroling power of the additive random noise and modifying the error signal. Simulation results demonstrate the effectiveness of the proposed approach.
