Design and Simulation of a Proposed Radon Based OFDM Transceiver

Abstract

In this paper, a class of discrete Radon transform, namely, finite Radon transform is proposed for the first time as a new technique in the realization of the orthogonal frequency division multiplexing (OFDM). The Radon transform is chosen in the OFDM structure to serve as a data mapper instead of the conventional data mapping techniques like the phase shift keying (PSK) mapping, in a way that ensure increasing the orthogonality of the system. The Fourier domain approach is found here to be the more suitable way for obtaining the forward and the inverse of the Radon transform. It is shown that this new application increases the orthogonality significantly due to the use of the inverse Fourier transform twice, namely, in the data mapping and in the sub-carrier modulation also, due to the use of an efficient criterion in determining the mapped data, which is called the optimal ordering criterion
