A Novel Approach of Implementing an FFT Algorithm on OFDM System
A Novel Approach of Implementing an FFT Algorithm on OFDM System
In this paper, we make insightful assessment of the computational performance of orthogonal frequency division multiplexing (OFDM) system in terms of complex calculations required using different Fourier transform techniques. We briefly introduce the different transform technique, viz. discrete Fourier transform (DFT) and various types of fast Fourier transform (FFT) as 2-radix FFT, 4-radix FFT etc. Underpinning the existing techniques, we propose a new FFT approach that can be applied to an OFDM system with less computation complexity.

Abstract

In this paper, we make insightful assessment of the computational performance of orthogonal frequency division multiplexing (OFDM) system in terms of complex calculations required using different Fourier transform techniques. We briefly introduce the different transform technique, viz. discrete Fourier transform (DFT) and various types of fast Fourier transform (FFT) as 2-radix FFT, 4-radix FFT etc. Underpinning the existing techniques, we propose a new FFT approach that can be applied to an OFDM system with less computation complexity.
