We present a new algebraic algorithm for computing the discrete Fourier transform over arbitrary fields. It computes DFTs of infinitely many orders n in O(n log n) algebraic operations, while the complexity of a straightforward application of the known FFT algorithms can be Ω(n1.5) for such n. Our algorithm is a novel combination of the classical FFT algorithms, and is never slower than any of the latter. As an application we come up with an efficient way of computing DFTs of high orders in… CONTINUE READING
