Abstract

The additive FFT algorithms of the preceding two chapters make no explicit use of the multiplicative structure of the indexing set. We will see how the multiplicative structure can be applied, in the case of transform size N = RS, where R and S are relatively prime, to design an FT algorithm that is similar in structure to these additive algorithms but no longer requires the twiddle factor multiplication. The idea is due to Good [2] in 1958 and Thomas [8] in 1963, and the resulting algorithm is called the Good-Thomas Prime Factor algorithm (PFA).
