This paper presents the implementation of fast Fourier transform (FFT) circuit for OFDM demodulation system. This FFT circuit computes transforms of any complex points independent of radices. This FFT circuit consists of several stages with the reconfigurable butterfly circuit. This paper describes a structure of the reconfigurable butterfly circuit and FFT processor.
