Analytical discussion of vortex-centric wireless OFDM systems for short-range applications

This paper presents wireless system considerations and theoretical analysis of the multiplexing scheme intended for the employment in the short-range communications. The primary objective of this paper is to develop a comprehensive analytical investigation into the radio frequency (RF) systems involving the orbital angular momentum (OAM) of the electromagnetic (EM) wave; as a sophisticated and generalised alternative solution for the wireless subsystems deployment realisation. The analysis has been conducted based on the vortex beam generating concepts, incorporating the intrinsic potential components of the modified orthogonal frequency-division multiplexing (OFDM) parameters.
