OFDM transceiver design using C

Abstract

The aim of this paper is to design a baseband orthogonal frequency division multiplexing (OFDM) [1]–[2] transceiver including 8 point Fast Fourier Transform (FFT), 8 point Inverse Fast Fourier Transform (IFFT) [3] core processor, DPSK modulator[4], demodulator serial to parallel and parallel to serial converter blocks in C language. The main challenge is to derive the algorithm for Fast Fourier Transform (FFT) and Inverse Fast Fourier Transform (IFFT). There are many algorithms available that can implement FFT and IFFT.
