A Novel Approach of implementing an FFT Algorithm on OFDM system

摘要：

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. We have also discussed about a new FFT approach that can be applied in an OFDM system and shown comparison of it with other FFT techniques.
