  • Abstract
    Reasons are suggested why the split-radix algorithm is better than any single-radix algorithm on length-2m DFTs (discrete Fourier transforms). The split-radix approach is generalized to length- pm DFTs. It is shown that whenever a radix-p2 outperforms a radix-p algorithm, a radix-p/p2 algorithm will outperform both of them. As an example, a radix-3/9 algorithm is developed for length-3 m DFTs
