Wolf-Dietrich Bukow,Erol Yildizalgorithms will now be designed corresponding to transform sizes given as a product of three or more factors. In general, as the number of factors increases, the number of possible algorithms increases.

Der Umgang mit der Stadtgesellschafte multiplicative structure can be applied, in the case of transform size . = ., where . and . 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 Th

Also, each size requires a different algorithm. There is no uniform tructure that can be repeatedly called upon. In this chapter, a technique

Reordering input and output data relative to a generator of ., the p-point FT becomes essentially a (p-1) x (p-1) . matrix action. We require 2(p-1) additions to make this change.

In fact, we will give a procedure for designing algorithms for transform size . = . a prime not dividing ., whenever an algorithm for transform size . is given. We will also include FT algorithms for transform size 4., where . is a product of distinct odd primes.

Cooley-Tukey FFT Algorithms,main idea is to use the additive structure of the indexing set . to define mappings of input and output data vectors into two-dimensional arrays. Algorithms are then designed, transforming two-dimensional arrays which, when combined with these input/output mappings, compute the N-point FT. The stride permutations of chapter 2 play a major role.
