Realizatsiya diskretnogo veyvlet-preobrazovaniya v sisteme ostatochnykh klassov spetsial'nogo vida
Anikueva O.V., Lyakhov P.A., Chervyakov N.I.
Abstract
In article the design method the wavelet filter in RNS is offered. It is shown that RNS pos-sesses high potential for increase in productivity of filters as in the considered task performance only of operations of addition and multiplication which can be calculated very quickly in a modular form is required. On the example of Dobesha’s filter Db4 it is shown how it is possible to transform coefficients from a position numeral system to RNS. Results of modeling showed that the rounding error which is inevitably arising upon such transition doesn’t cause significant deviations in operation of the filter.

Veroyatnostnoe opisanie yavleniya tsentrobezhnoy oshibki pri peredache bezyzbytochnykh kodov po gaussovskim kanalam
Rassomakhin S.G., Malofey O.P., Malofey A.O.
Abstract
The phenomenon that occurs when the transmission of numerical codes on Gaussian chan-nels, leading to an increase of the mean square error recovery numbers as their distance from the center of the allowable range. Justified the name of this phenomenon as “centrifugal er-ror” transmission, the basic functions and numerical characteristics of its probabilistic description. Possible ways to eliminate the negative impact of this type of distortion to improve the noise immunity of transmission systems of numerical information.

Pomekhoustoychivost' skhemy priema OFDM-signalov v kanale s pamyat'yu
Slipenchuk K.S., Bel'skiy K.A.
Abstract
The technology of orthogonal frequency OFDM multiplexing is hosed on for motion of multi frequency signal. The block of consistent information symbols converts in block of parallel symbols; in which every information symbol satisfy certain frequency of the multi frequency signal. Increasing the spectral efficiency of the OFDM system will facilitate the development of advanced mobile networks.

Povyshenie kachestva peredachi potokovykh dannykh v setyakh VPLA s pomoshch'yu PULL-PUSH-podkhoda
Abilov A.V., Vasil'ev D.S.
Abstract
In this paper, we analyze quality of video streaming in Flying Ad Hoc Networks (FANETs) with help of an NS-3 simulation tool. Considered network topology consists of source, destination and relay nodes and uses AODV and OLSR routing protocols. We estimate quality of video streaming based on average chunk delivery ratio PDRave and average application layer data deli-very speed Rave. We developed data delivery algorithm using PULL-PUSH approach to improve quality of video streaming. This paper presents performance investigation of developed algorithm in considered network topology with AODV and OLSR routing protocols.

Kiral'nyy metamaterial dlya chastotno-selektivnoy kontsentratsii energii sverkhvysokochastotnogo izlucheniya
Osipov O.V., Pocheptsov A.O., Yurasov V.I.
Abstract
Electrodynamics analysis of metamaterial formed by periodically placing thin-wire multiturn spiral elements in a homogeneous dielectric container. Solved the problem of reflection of a plane electromagnetic wave from said metamaterial and the coefficients of reflection and transmission main and cross-polarized components of the field. It is proved that the metamaterial can convert radially incident super high-frequency (UHF) radiation at the resonant frequency surface waves. Calculated frequency dependence of moduli of the coefficients of reflection and transmission main and cross-polarized components of the field at different geometrical dimensions of the container and spiral inclusions. It is shown that the resonant frequency of the incident field in the conversion surface waves satisfy a relation similar to the Bragg condition for the crystalline environment.
