Документ Model of impact interferences on radiocommunication systems for special communications(NTU "KhPI", 2017) Romanenko, Igor; Shyshatskyi, AndriiAs the analysis of recent events in the East of Ukraine shows, radio communication is the transport basis for the construction of telecommunication networks of special purpose. In view of the above, the subject of study in the article are the special radio communication systems, operating in a complex electronic environment. The purpose of this articleis to develop a mathematical model for the effects of interference on systems of special radio communication. The taskssolved in the course of the study: a formal description of various types of noise that is used to suppress the systems of special radio communication; analytical representation of the probability of a bit error for signals with different types of modulation under the influence of the main types of deliberate disturbances; development of recommendations for increasing the noise immunity of special radio communication systems with different types of signal modulation under the influence of deliberate interference. In the course of the study, the following method swere used: signal theory, radiocommunication theory and the theory of potential impedance protection. In the course of the study, analytical dependencies were obtained that allow us to calculate the probability of a bit error in the effect of intentional interruptions for different types of signal modulation. Conclusions: the proposed mathematical model should be used in the analytical modeling and evaluation of the performance of broadband radio networks of a special purpose taking into account the combined action of the additive white Gaussian noise and structural impediment, algorithms for the formation and processing of signals at the physical level, as well as the properties of the radio channel.Документ Analysis of modern condition of military radiocommunication system(НТУ "ХПІ", 2017) Romanenko, Igor; Shyshatskyi, AndriiAim of the article is to conduct an analysis of military communications systems that were used in the area of conducting antiterrorist operation in the Donetsk and Lugansk regions. The article analyzes the modern facilities of military communication, namely: military radiocommunication systems, military satellite communication systems, military systems of radio relay and tropospheric communication. The advantages and disadvantages of each type of communication are considered, the causes of their occurrence were considered, and the ways of solving these reasons in the future were substantiated. An analysis of the main technical characteristics of military communication systems, opportunities, advantages and disadvantages has been conducted. The perspectives for the development of military communication systems have been determined on the basis of the analysis of the military facilities of communication used in the article, which are used in the region of the antiterrorist operation in the Donetsk and Lugansk regions. To eliminate the problematic issues mentioned in the article, the authors of the article are proposing to launch their own military satellite for the needs of the Armed Forces of Ukraine; To develop new models of military communication; To conduct deep modernization of the existing radio stations, command-staff cars, radio relay and tropospheric stations; To integrate telecommunications equipment adopted in the last years into a single information space of the Armed Forces of Ukraine, as well as to reach agreement with representatives of leading telecommunication equipment manufacturers regarding the transfer of technologies and deployment of production in the territory of Ukraine.
