Download Fast Fourier Transforms by C. Sidney Burrus, at al., This book uses an index map, a polynomial decomposition, an operator factorization, and a conversion to a filter to develop a really general and efficient description of quick algorithms to calculate the discrete Fourier transform (DFT). The work of Winograd is outlined, chapters by Selesnick, Pueschel, and Johnson are enclosed, and computer programs are provided.
