A Reconfigurable Butterfly Architecture for Fourier and Fermat Transforms

Résumé

Reconfiguration is an essential part of Soft- Ware Radio (SWR) technology. Thanks to this technique, systems are designed for change in operating mode with the aim to carry out several types of computations. In this SWR context, the Fast Fourier Transform (FFT) operator was defined as a common operator for many classical telecommunications operations [1]. In this paper we propose a new architecture for this operator that makes it a device intended to perform two different transforms. The first one is the Fast Fourier Transform (FFT) used for the classical operations in the complex field. The second one is the Fermat Number Transform (FNT) in the Galois Field (GF) for channel coding and decoding.
