High-Speed Parametric FPGA Implementation of FFT/iFFT Blocks for OFDM Transceivers

FFT and iFFT are ones of the most useful blocks in DSP systems. Since the speed of calculation of the result is one of the important factors of this  basic block, in this paper we develop a new method for FFT/iFFT implementation which leads to better computation speed in comparison with other common implementation methods.
