초록
In multi-channel active noise control (ANC) systems, online secondary-path modeling (OSPM) using the auxiliary noise signal is often applied. However, the additive noise signal may contribute to the residual output noise. In this paper, the conventional noise power scheduling, utilized for single-channel ANC with OSPM, is further extended to multi-channel ANC. Simulation results demonstrate that the proposed approach yields better ANC performance, compared with conventional multi-channel ANC methods.
