In this paper, we implement the IFFT/FFT(Inverse Fast Fourier Transform/Fast Fourier Transform) adapted the IEEE 802.11a-1999, which is a standard of the High-speed Wireless LAN using the OFDM(Orthogonal Frequency Division Multiplexing) method. The proposed IFFT/FFT module is designed to minimize error and optimize architecture, using the 64-point R4SDC(Radix-4 Single-path Delay Commutator) method.
The proposed IFFT/FFT module is designed by using the Verilog HDL and implemented by using the Samsung STD90(0.35㎛ 3.3 V)library.
