Журнал радиоэлектроники. 2002. No. 7.
S.A. Tiraspolsky, Gerebryakov G. V.
In this paper we investigate comparison methods of different geometric configurations of adaptive antenna arrays for communications on purpose to estimate directions-of-arrival (DOA) of several external signals. The investigated antenna configurations have four elements and eleven wavelengths array size. The best high-resolution algorithm and the best array configuration are defined by numerical simulations.

This book presents established and new research on the close connections between graph games and systems of logic, particularly existing and newly designed modal logics. The volume utilizes two graph games – the sabotage game and the hide-and-seek game – to demonstrate the natural interplay between designing new graph games and exploring new kinds of ...

In the present paper we consider an Ω-stable 3-diffeomorphism with a solid or thickened surfaced non-trivial basic set. Such basic sets include, for instance, all one-dimensional expanding attractors and those two-dimensional basic sets that are not expanding. We prove that the chain recurrent set of every such a diffeomorphism necessarily contains at least two non-trivial ...

Пусть симплекс с целочисленными вершинами - содержащий ровно одну целочисленную точку, отличную от своих вершин. В работе доказывается, что если точка находится во внутренности симплекса или в относительной внутренности некоторой гиперграни симплекса, то объем симплекса ограничен величиной, зависящей только от размерности, в противном случае объем симплекса может быть сколь угодно большим. Этот результат применяется для вывода асимптотической формулы для среднего числа вершин полиэдров ...

Business process management employs process models and event logs to represent the behavior of the information systems under study. Traditional case-centric notions consider the order of activities and events in isolated process instances. The emerging field of object-centric processes challenges this assumption by putting objects in the center. Object-centric process mining and modeling approaches identify ...

A concept of using MIMO technology in millimeter range wireless communications systems with orthogonal frequency division multiplexing is considered. The concept is based on dividing transmitting and receiving multi-element antenna arrays into separate sub-arrays with analogue radiation pattern shaping and on using two most powerful space sub-channels for information transmission. Sequence and structure of transmitted ...

In a wireless communication system, signals sent into the channel interact with the environment in a very complex way. Thereby transmitted signals may be subject to many forms of degradation among which there are causes of multipath propagation: • Reflections due to obstacles with the size greater than a wavelength; • Refractions due to the ...

Рассмотрены системы связи декаметрового диапазона, работающие в условиях многолучевого
ионосферного пространственного канала. С помощью имитационного моделирования на физическом
уровне исследованы основные характеристики системы (вероятность битовой и блоковой ошибки, про
пускная способность). Показано, что в условиях частотно-селективного канала в полосе 3 кГц линейный
алгоритм эквализации обеспечивает высокую эффективность подавления межсимвольной помехи для
всех скоростей передачи данных, кроме самой высокой. ...

Electrodermal activity (EDA) in humans is one of the integrative parameters reflecting important psychophysiological processes. One of the promising applications of EDA is the assessment over long time intervals, which allows the identification of specific tendencies of the human body. We have developed a mobile wireless device that allows registering EDA for hours, days, and ...

One of the principal specifics of future 6G systems operating in the subterahertz and terahertz frequency bands (0.1–0.3 THz and 0.3–3 THz) is that a part of the base station (BS) coverage will be located in the near-field region. As in this region, the signal received power (SRP) heavily depends not only on the separation ...

Nowadays, the Direction of Arrival (DoA) estimation problem attracts much attention because of emerging use cases for wireless networks. DoA is beneficial for Reconfigurable IntelligentSurfaces, indoor localization, and various navigation and sensing applications, such as gesture recognition and home monitoring. The Multiple Signal Classification (MUSIC) algorithm is very promising for DoAestimation because it provides better ...
