摘要：通过短时傅里叶变换算法原理分析,运用Max+plus II设计了现场可编程逻辑器件实现高速短时傅里叶变换,该结构充分利用蝶形单元运算特点,在满足时间分辨率及频率分辨率的基础上降低了运算复杂度,并在高速率运行时钟下节省了硬件资源.最后,进行了仿真研究分析,达到了信号语谱设计要求.
It is designed field programmable logic devices and realized high speed structure of the short-time Fourier transform In this paper,through the principle analysis of short time Fourier transform algorithm using M ax ＋ plus II.We make full use of the butterfly unit operation characteristics,the structure to meet the time resolution and frequency resolution on the basis of reduced the computation complexity,and under the high speed running clock saving hardware resources.Finally,It had been carried on the simulation analysis.It shows reaching the frequency signal spectrum design requirements.
