Abstract

In this paper, we are designed and verified a FFT/IFFT processor that is possible from the wireless LAN environment which is adopted international standard of the IEEE802.11a. The proposed architecture of the FFT/IFFT has Radix-2 64point SDF(single-path delay feedback) Pipeline technique and DIF(Decimation in Frequenct) structure. The FFT/IFFT processor has each 8 bit complex input-output and 6 bit Twiddle factor. we used Max-PlusII for simulation and can see that processor is properly operated
