Abstract

This article focuses on the application of AP algorithms in active noise control systems. The active noise control system is a real-time tracking noise signal, which is then cancelled with an opposite signal to achieve noise reduction. Therefore, the active noise control system requires high real-time performance. In a multi-channel active noise system, a large amount of calculation is a key factor that causes the real-time performance of the system to decrease. This paper simplifies the system structure based on the existing fast AP algorithm, further reduces the system overhead and achieves the purpose of improving real-time performance. And through the DSP chip, an experimental platform for the active noise control system was built, and the proposed algorithm was validated for practical results.
