数学计算  This article describes a new efficient implementation of the Cooley-Tukey fast Fourier transform (FF

This article describes a new efficient implementation of the Cooley-Tukey fast Fourier transform (FFT) algorithm using C++ template metaprogramming. Thank to the recursive nature of the FFT, the source code is more readable and faster than the classical implementation. The efficiency is proved by pe ...

学术论文  基于FPGA的快速傅立叶变换.rar

随着数字电子技术的发展，数字信号处理广泛应用于声纳、雷达、通讯语音处理和图像处理等领域。快速傅立叶变换(Fast Fourier Transform，FFT)在数字信号处理系统中起着很重要的作用，FFT 有效地提高了离散傅立叶变换(Discret Fourier Transform，DFT)的运算效率。处理器一般要求具有高速度、高精度、大容量和实时处理的性能 ...

学术论文  基于FPGA的FFT数字处理器的硬件实现

DFT(Discrete Fourier Transformation)是数字信号分析与处理如图形、语音及图像等领域的重要变换工具,直接计算DFT的计算量与变换区间长度N的平方成正比.当N较大时,因计算量太大,直接用DFT算法进行谱分析和喜好的实时处理是不切实际的.快速傅里叶变换(Fast Fourier Transformation,简称FFT)使DFT运算效率提高1~2个数量级.本 ...
