A general in-place and in-order prime factor FFT algorithm

  • Published:
Journal of Electronics (China)

Abstract

Starting from an index mapping for one to multi-dimensions, a general in-place and in-order prime factor FFT algorithm is proposed in this paper. In comparing with existing prime factor FFT algorithms, this algorithm saves about half of the required storage capacity and possesses a higher efficiency. In addition, this algorithm can easily implement the DFT and IDFT in a single subroutine.
