对于一个任意给定的信号, 判断其傅里叶变换是否存在一直是尚未解决的问题.
由于此问题在信号分析类课程的教学或工程应用中常给人们带来困扰, 该文对此进行了分析 …

Commensal radar [1] is an attractive solution to low-cost air-traffic surveillance. This paper
proposes an alternative approach using a recursive Fourier transform for Doppler …

Abstract The Discrete Fourier Transform (DFT) has played a fundamental role for signal
analysis. A common application is, for example, an FFT to compute a spectral …

The sliding discrete Fourier transform provides an alternative to the FFT, permitting a custom
choice of frequency decomposition which outputs an update after each input sample. The …

Digital filters for recursively computing the discrete Fourier transform (DFT) and estimating
the frequency spectrum of sampled signals are examined, with an emphasis on magnitude …

This paper provides a novel way of trading increased resource utilisation for decreased
latency when computing a single Discrete Fourier Transform on the FPGA. Analysis …
