A Review on Reconfigurable Fourier and Fermat Transforms for Software Radios
B. B. Godbole · 2014
Reconfiguration is an essential part of Software Ra dio (SR) technology. The systems are designed for c hange in operating mode with the aim to carry out several types of computations. In this SR context, the Fas t Fourier Transform (FFT) operator is defined as a common operator for many classical telecommunications operati ons. It reviews a new architecture for this operator that m akes 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) used for the finite operations in the Galois Field (GF). This operat or can be reconfigured to switch from an operator dedicated t o compute the FFT in the complex field to an operat or which computes the FNT in the Galois Field.
