离散分数阶Fourier变换的高速FPGA实现

High speed FPGA implementation of discrete fractional Fourier transform

介绍了一种直接在时域和频域对信号进行离散的数值计算方法。针对工程实际,提出了一种基于FPGA的硬件实现方法,同时给出了具体的算法和计算机仿真结果。

A numerical method of discrete fractional Fourier transform is introduced in this paper, which samples the signal in time domain and frequency domain directly. The numerical method based on FPGA platform, the algorithm and simulation results are also given.
