Abstract
On the basis of theoretical calculations confirmed by modeling, the principles of construction of the ultra-wideband radio communication system in the terahertz frequency range on the basis of electronics technology using the harmonic signal as a carrier of information have been substantiated. The analysis of the current state of the problem was made and the task of creating a terahertz telecommunication system of broadband radio access with a gigabit bandwidth in the range of operating frequencies 130–134 GHz was performed. Terahertz frequency range areas that are most suitable for use in radio relay communication lines are selected Physical simulation of ultrahigh-speed shaper based on multi-frequency multistelection of modulated OFDM digital streams has been carried out, bench testing and optimization have been performed to achieve the maximum bandwidth of the channel for transmission of digital stream information in the format of Ethernet to the full channel speed at full duplex up to 1.2 Gbit/with. On the basis of the generalization of the results of theoretical research and experimental work, the analysis of the existing radio relay element base, the design of the main nodes of the receiving and transmitting path of a telecommunication system with a gigabit throughput in the frequency range 130–134 GHz. The scientific novelty of the work consists in generalization and development of the theory of distribution, formation and measurement of terahertz signals, in the development of multifrequency multiplexing method and the formation of modulated OFDM digital streams in the terahertz frequency range and the development of the principles of functional design on the basis of electronics technology using the harmonic signal as a carrier of information in the transceiver tract of telecommunication system with gigabit bandwidth in terahertz frequent range.
