    Methods of estimation of the channel state of air defense systems
    (NTU "KhPI", 2017) Zhyvotovskyi, Ruslan; Petruk, Sergii
    The subjectof study in the article is the methods for assessing the state of channels of air-conditioning complexes operating in a complex electronic environment. The methods discussed in this article include the method of least squares, the method of mean square deviation, channels estimation methods for iterative methods of signal processing at reception, suboptimal algorithms for iterative channel estimation and information symbols based on t he maximum likelihood method, linear unbiased estimation methods with minimal dispersion and methods of linear estimation with a minimum of mean square deviation. The purposeof the study is to conduct an analysis of existing methods for assessing the state of the air defense airway channels in the conditions of radio-electronic suppression and multi-beam propagation of radio waves. The tasks solved in the study: a mathematical description of known methods for assessing the state of the channels and the development of recommendations for the synthesis of optimal methods for assessing the state of the channels. The methods used in the study: theory of communication, theory of noise i mmunity and electronic warfare. In the course of the study, recommendations were obtained for the synthesis of optimalmethods for assessing the status of channels under the conditions of intentional interference. Conclusions: in the presence of sufficient a priori information about the transmission of information symbols, the best results on the criterion of the ratio ofaccuracy of estimation and complexity of implementation is demonstrated by the algorithm of linear estimation at the minimum of the mean-square deviation. In the absence of sufficient a priori information about the transmission of symbols, the best optionis an unmatched estimate for the minimum of the smallest squares. In order to increase the accuracy of the evaluation of the transmission characteristics of the air defense airway channels inthe conditions of a complex electronic environment it is advisable to use iterative principles.

    Justification of perspectives directions of upgrading radiocommunication systems of Armed Forces Ukraine
    (НТУ "ХПІ", 2017) Zhyvotovskyi, Ruslan; Petruk, Sergii
    Aim. In the article explore issues and directions of the innovative approach to the development of automated complexes and radio communication facilities for special purposes. During the research it was determined that the effectiveness of the military radio communication system would be improved by facilities of modernization of the latest facilities of radio communication of foreign production or by improving the existing system of military radiocommunication. Presented directions and features of leading research and development works for the improvement and development of channels and systems of military radio communication, the creation of nodes and centers of radio communication, automated complexes and radio communication of special purpose were presented. Was given generalized approach to the construction of the system of automated radio communication, antenna-hardware complexes, software and hardware complexes of radio prediction and planning of use of radio frequency resource. Conclusions. According to the results of the conducted researches, conceptual decisions about the system engineering and technological reconfiguration of the existing radio communication system are proposed, which will allow to work in the automated radio networks as part of the radio centers of information and telecommunication units; to unify the facilities and complexes of radio communication with facilities of communication and automation, to provide counter work with the equipment of the old park, as well as to construct a fundamentally new radio communication system with the ability to calculate the planning and forecasting of the radio frequency resource.
