炮兵自适应护耳器的设计

The design of an adaptive earmuffs for artilleryman

介绍了TI公司定点系列中TM S320VC5416DSP的结构、特性,讨论了利用该芯片基于LM S算法及FX-LM S算法的自适应护耳器的设计原理、语音提取和噪声对消的方案及软硬件实现中需注意的问题。

This paper introduces the structure and main features of TMS320VC5416, the 16-bit fixed-point DSP of TI company. It discusses the principle and scheme of the adaptive filter using LMS and FX-LMS algorithm to distill voice form noises and to cancel noises with this kind of DSP. It also describes the problems during the process of designing the hardware and software.
