A data and error complexity analysis of two algorithms for fast Fourier transforms is presented. The results show that the algorithm using decimation in time is "equivalent" to the one using decimation in frequency. This is also supported by the numerical experiments described.
In this paper, we propose a new approach for computing 2D FFT's that are suitable for implementation on a systolic array architecture. Our algorithm is derived in this paper from a Cooley decimation-in-time algorithm by using an appropriate indexing process. It is proved that the number of multiplic
