Abstract :
This paper deals with the development of reusable FFT cores for OFDM in the light of the new features offered by modern FPGAs and synthesis tools. A pipelined and a sequential architecture have been selected as case studies to show how the requirements of various OFDM standards affect the choice of the optimal FFT architecture
