Design of FFT Processor for OFDM

OFDM용 FFT 프로세서의 설계

This paper present the architecture and design of FFT processor for the OFDM modulation. The OFDM modulation have a merit that use frequecncy efficiently and robust ISI. It needs FFR to have fast and large number of points. Moreover, this FFT design has pipeline architecture. R2$^2$SDF architecture for FFT processor has more advantage others. Therefore this paper present FFT processor used R2$^2$SDF architecture.
