"WebRadix-2 Cooley-Tukey# As mentioned in the introduction to this chapter, there are many algorithms which are collectively referred to as “Fast Fourier Transforms”. In this section, we’ll see one of the earliest methods, (re-)discovered in 1965 by Cooley and Tukey [ CT65 ] , which can accelerate DFT calculations when \(N\) is an integral power of 2: \(N = 2^K\) .

WebThe mixed-radix algorithm is based on sub-transform modules -- highly optimized small length FFTs which are combined to create larger FFTs. There are efficient modules for factors of 2, 3, 4, 5, 6 and 7. The modules for the composite factors of 4 and 6 are faster than combining the modules for @math {2*2} and @math {2*3}.
