Efficient algorithms of FFT butterfly for OFDM systems

Abstract

In this article, the FPGA realization of FFT processor in OFDM systems is considered. After the analysis of conventional FFT architectures, parallel butterfly algorithm is proposed. And then, based on it, dual butterfly algorithm is put forward. The FFT architecture with these algorithms has higher throughput and requires relatively small areas.
