摘　　要：设计并实现了一种适用于封闭空间的、基于TI TMS320VC5416 DSP的单通道有源前馈噪声控制系统,详细阐述了有源噪声控制采用的FLMS算法和次级通路建模中采用的LMS算法,给出了程序流程图,介绍了硬件结构,并在封闭空间内进行实验。实验结果表明,该系统具有良好的降噪效果。A single-channel feedforward active noise control system is designed and implemented in this paper. Based on TMS320VC5416 DSP and used in close room, this paper presents the LMS algorithm used in the secondary path modeling and Filtered- XLMS algorithm used in noise control. It also presents the hardware structure and software flow. We experimented in a close room, the experimental data proved a good result.
