The Cooley–Tukey algorithm, named after J. W. Cooley and John Tukey, is the most common fast Fourier transform (FFT) algorithm. It re-expresses the discrete Fourier transform (DFT) of an arbitrary composite size [math]\displaystyle{ N = N_1N_2 }[/math] in terms of N 1 smaller DFTs of sizes N 2 , recursively , to … See more This algorithm, including its recursive application, was invented around 1805 by Carl Friedrich Gauss, who used it to interpolate the … See more More generally, Cooley–Tukey algorithms recursively re-express a DFT of a composite size N = N1N2as: 1. Perform N1 DFTs of size N2. 2. Multiply by complex roots of unity (often called the twiddle factors). 3. … See more A radix-2 decimation-in-time (DIT) FFT is the simplest and most common form of the Cooley–Tukey algorithm, although highly optimized Cooley–Tukey implementations typically use other forms of the algorithm as described below. … See more There are many other variations on the Cooley–Tukey algorithm. Mixed-radix implementations handle composite sizes with a variety of (typically small) factors in addition to two, usually (but not always) employing the O(N2) … See more WebThe Cooley–Tukey algorithm, named after J.W. Cooley and John Tukey, is the most common fast Fourier transform (FFT) algorithm.
