Realization of active noise control platform based on FPGA

Abstract

In this paper, an active noise control platform for the vehicle is built based on FPGA. The platform can correctly collect the speed, vibration acceleration and noise of the vehicle in real time, and provide a hardware platform for the related noise reduction algorithm. Compared with the traditional serial processing based acquisition system, the platform can strictly guarantee the time synchronization of multiple signals, and its scalability allows users to easily increase the number of channels according to their own needs, and no additional processor is required. FPGA programmability can guarantee the full verification and design of noise reduction algorithm. The construction of the whole platform provides a strong foundation for the continuous research of active noise reduction.
