The object of the study is the telecommunication broadband radio systems in themillimeter and terahertz waves. The purpose of the work is to find the principles, methods of constructing new radio systems in millimeter and terahertz waves based on the characteristics of the propagation of radio waves in the indicated wavelength ranges and the application of a quasi-optical model, both for open systems and for mobile system in the urban scenario. The purpose of the study is the multipath model of propagation of radio waves, energy and spectral efficiency, the energy model of the radio link budget, the zone of amplification of signals outside the line of sight (NLOS, non-line-of-sight) due to diffraction and reflections of millimeter and terahertz waves. The paper analyzes: the features and prospects of using millimeter and terahertz waves for promising telecommunication systems; hybrid technologies for the realization of RoF systems (radio-over-fiber) quasi-optical energy model of radio systems calculation; methods of increasing the energy efficiency of millimeter and terahertz waves systems5481 Product Description popup.authors Жукова Олена Ромуальдівна Кременецька Яна Адольфівна Морозова Світлана Володимирівна popup.nrat_date 2020-04-02 Close
