| Abstract(in English) | In active noise control (ANC) systems, online acoustic feedback path modeling and neutralization (FBPMN) is needed: 1) to solve the potential instability problem associated with fix/time-varying acoustic feedback path, and 2) to improve the noise-reduction-performance (NRP). Auxiliary noise injected for online FBPM degrades the NRP of the ANC systems. The solution to the problem is to use scheduling of auxiliary-noise-power (ANP). The previously proposed ANP scheduling strategy needs two tuning parameters. In this paper a self-tuned ANP scheduling strategy with matching step-size for adaptive FBPMN filter is proposed. The advantage of the proposed scheme is that no tuning parameters are required for ANP scheduling, and improved steady-state NRP is achieved. The simulation results verify the effectiveness of the proposed method. |
