Results of time-frequency representation of such signals are presented and discussed.Item Multimatrix processor for cyberspace analysis(Видавництво Львівської політехніки, 2012) Hahanov, Vladimir; Chumachenko, Svetlana; Baghdad, Ammar Avni; Maksimov, M.The structural model of high-speed ultimatrix processor designed for fast and accurate earch of information objects in cyberspace is described is proposed. It enables to increase considerably (x10) the speed of diagnosing single and/or multiple faults.Item A problem of providing of coherent treatment of signals is during realization of non-coherent methods of radio-location(Видавництво Львівської політехніки, 2012) Shyncaruk, Oleg; Chesanovskiy, IvanThe questions of rise of coherence processing of radiolocation signals are examined in non-coherence impulsive facilities of radio-location.Item Server virtualization management of corporate network with hyper-v(Видавництво Львівської політехніки, 2012) Kovalenko, TarasOn a paper main tasks and problems of server virtualization are considerate. Practical value of virtualization in a corporate network, advantages and disadvantages of application of server virtualization are also considerate.Item Identification with privacy protection based on data hiding(Видавництво Львівської політехніки, 2012) Holotyak, Taras; Voloshynovskiy, Svyatoslav; Prudyus, IvanIn many problems such as biometrics, multimedia search and retrieval, recommendation systems requiring privacy preserving similarity computations and identification, some binary features are stored in the public domain or outsourced to the third parties that might raise certain privacy concerns about the original data. To avoid this privacy leak, privacy protection is used. In the most cases, the privacy protection is uniformly applied to all binary features resulting in the data degradation and corresponding loss of performance. To avoid this undesirable effect we propose a new privacy amplification technique that is based on data hiding principles and benefits from side information about bit reliability a.k.a. soft fingerprinting. In this paper, we investigate the identification rate vs. privacy-leak trade off. The analysis is performed for the case of perfect match between the side information shared between the encoder and decoder as well as for the case of partial side information.Item Monopulse-frequency temporal processing of unknown signals based on LFM - fourier transform in passive systems radiomonitoring(Видавництво Львівської політехніки, 2012) Antonyuk, Volodymyr; Kalyuzhniy, Mykola; Prudyus, Ivan; Nichoha, VitalijPrinciples of combination of dispersive-time and digital signal processing methods in problems of identification, evaluation parameters, recognition and identification of complex signals and means that they emit.Item Results of the dynamic flow-based queue balancing model research(Видавництво Львівської політехніки, 2012) Lemeshko, Olexandr V.; Ali, Ali S.; Semenyaka, Maxim V.The paper presents the flow-based model that was designed for solving dynamic queue balancing problem on the telecommunication network routers. Within the proposed model the problem of queue balancing was reduced to solution of the linear programming optimization problem. The research of the queue balancing process was performed by using flow-based model in regard to improve quality of service in multiservice network nodes.Item Radiowave methods of non-destructive testing(Видавництво Львівської політехніки, 2012) Liske, Oleksiy; Yakymiv, Roman; Melnychuk, AndriiIn this paper the analysis of existing methods of radiowave non-destructive testing which allow to detect the presence and depth of extraneous metal and dielectric defects in controlled objects is given.Item The 2D – 3D – 2D' method for communication system research(Видавництво Львівської політехніки, 2012) Pelishok, VolodymyrThis paper contains a description of the proposed 2D – 3D – 2D' method, which allows transition from the existing two-dimensional dependences to the ancillary three-dimensional dependences and follows to the required two-dimensional dependences. It helps to simplify the research.Item Efficiency increase of information services in 3G and 4G networks, using MIMO-systems(Видавництво Львівської політехніки, 2012) Yaremko, OlegThe basic idea of a CDMA system to overcome the multipath problem is built on the fact that a spread spectrum signal has a much wider bandwidth occupancy than its original baseband signal, such that the spread spectrum signal will offer a unique property that multipath diversity can be made possible due to its excellent time resolution derived from its very wide bandwidth signaling. A RAKE receiver can be used to resolve different multipath returns individually and combine them again in a coherent or non-coherent way, to achieve the multipath diversity capability, which has become one of the most important technical features that make CDMA a very attractive multiple access technology for 2G and 3G wireless communications.Item Зміст до «Сучасні проблеми радіоелектроніки, телекомунікацій, комп'ютерної інженерії»(Видавництво Львівської політехніки, 2012)Item Comparison of the excitation efficiency of the biological structures of single-and bipolar pulse(Видавництво Львівської політехніки, 2012) Romanyshyn, Yuriy; Smerdova, TatjanaThe article compares the efficiency of excitation of biological structures and electrical single bipolar pulse.Item Successive interference cancellation methods in tree algorithms of random multiple access(Видавництво Львівської політехніки, 2012) Tur, Bogdan; Yahya, HusseinIn this paper are given the main idea of using Successive interference cancellation method in tree algorithms of random multiple access.
