Abstract

In this world, because of advancing in technology, there is a growing need for people to communicate with each other without delay. Speed is very important in all aspects. It can be improved by reducing arithmetic complexity. At the same time accuracy is also very important. In general, FFT/IFFT is used as a modulation/demodulation kernel in the OFDM
system. Several techniques are introduced for FFT/IFFT like radix 2 FFT, radix 4 FFT, split radix FFT, conjugate pair FFT, etc. Among which split radix FFT is an effective method to reduce arithmetic complexity. In this paper, two different VLSI architectures of FFT using radix 2 and split radix algorithms are designed by floating point arithmetic.

Keywords: OFDM transmitter/receiver, FFT/IFFT, DFT, split radix, radix 2 algorithm
