THE INCREASE OF THE ENERGY EFFICIENCY OF THE RADIO EQUIPMENT BASED ON THE USE OF MODULATION BY ORTHOGONAL HARMONIC CARRIERS


Abstract

Most of the theoretical results, as well as methods using OFDM modulation, are obtained in order to increase the rate of information transmission with energy constraints and the bandwidth. For broadband radio access systems, this task is primarily due to the commercial purpose of these systems and the desire of the communications developers to provide high-speed wireless access to the Internet as much as possible at the same time. This article is devoted to the issue of increasing the energy efficiency of radio equipment using modulation orthogonal harmonic carriers under conditions of intentional interference and frequency-selective fading while ensuring a given level of reliability and speed of information transmission.
