摘要：A fast Fourier transform (FFT) is any fast algorithm for computing the DFT. The development of FFTalgorithms had a tremendous impact on computational aspects of signal processing and applied science. Thedecimation-in-time (DIT) fast Fourier transform (FFT) very often has advantage over the decimation-in-frequency(DIF) FFT for most real-valued applications, like speech/image/video processing, biomedical signal processing, andtime-series analysis, etc., since it does not require any output reordering. Upon comparison, the proposed algorithmbased on unsigned, signed and complex multiplier is fast than previous algorithm. This all design and experiments werecarried out on a Xilinx 6.2i Virtex-2p device family.
