Abstract

In this paper we present an approach to simplify the design of IFFT/FFT cores for OFDM applications, A novel software tool is proposed, called AFORE. It is able to generate efficient single and multiple mode IFFT/FFT processors. AFORE employs a parallel architecture, where the degree of parallelism can be varied. This way, the tool can find a trade off between area and processing time to meet the system specification. In order to assess the quality of the proposed approach, results are provided for some of the most widely used OFDM standards, such as, WLAN 802.11a/g, WMAN 802.16a, DVB-T.
