BINARY EXPONENT DIVISION METHOD FOR CONVERSION OF THE MINIMALLY REDUNDANT MODULAR CODE TO THE POSITIONAL CODE
Kolyada A.A., Chervyakov N.I., Kuchynski P.V., Chernyavsky A.F., Shabinskaya E.V.
Abstract
The paper is dedicated to the optimization procedures of the modular-positional conversion, which are based on the binary exponent division method. The optimization provides minimization of summary time spent and applying of accessible memory for tables. It is achieved by using of minimally redundant modular coding, and number systems with large bit radix, as well as the table-summatory technology of calculation.

DECODING POLAR CODES IN DECODER OF ARIKAN ON BASED INDEXES SOFT-DECISIONS
Gladkikh A.A., Chilikhin N.Y.
Abstract
An algorithm decoding of polar codes based on the procedure of forming integer indices soft decisions in sequential decoder Arikan properties using Tanner graph, which allows to reduce the bit error rate due to reduce the effects of a cascade of proliferation of erroneous decisions at each stage of data processing. A scheme for polar coding system erases the link using a wide range erasure to implement a generic method of forming integer indices soft decisions.

ABOUT NEW APPROACH FORMATION SIGNAL-CODE STRUCTURES WITH HIGH SPECTRAL EFFICIENCY
Zhilyakov E.G., Belov S.P., Starovoit I.A., Ushakov D.I.
Abstract
The paper proposes a new approach of forming spectrally efficient signal-code structures (SCS) based on used new orthogonal signal basis. Applying the basis of eigenvectors with the parameters whom agreed with communication channel allows you to get SCS spectral efficiency whom by 20% exceeds the currently used CCM OFDM.

GENERALIZED INVARIANT METHOD MESSAGING AND ASSESSMENT OF ITS INFORMATION SECURITY
Lebedyantsev V.V.
Abstract
In work the generalized invariant of linear communication channels in the form of the relation of volumes of the m-dimensional parallelepipeds formed in alarm space by the relevant groups of transmitted signals kept by channels is synthesized. The algorithm of transmission of messages using this invariant is developed. The assessment of information security of the generalized invariant method of transmission of messages is given.

ORGANIZATION OF THE EXCHANGE BY INFORMATION IN INDUSTRIAL NETWORK ON BASE OF THE MODULES TO SERIESES ADAM-4000
Kangin V.V., Lozhkin L.D.
Abstract
The Article is dedicated to questions to organizations of the exchange by information be-tween host-computer and module removed and portioned entering-conclusion to serieses ADAM-4000 (the company Advantech, Taiwan) in computer portioned system data accep-tance and management (KRSSDU). Host and worker to modules unite by means of industrial network on the base of the interface RS-485 with use protocol ASCII or Modbus. It Is Shown that problem of the exchange by information between host-computer and workers module entering-conclusion to serieses ADAM-4000 KRSSDU on the base of the industrial network can be solved facility of the ambience of the visual programming Delphi with use the structures DCB and CommTimeOuts. The Executed analysis mistake, which can appear when changing by information between host and workers module, is organized their categorization. On the grounds of called on studies is designed universal exhibit, allowing change the parameters of the adjustment COM (USB)-port and network address of the module ADAM-4055.

FORMATION OF IMAGES OF MODOVY LIGHT BUNCHES AT DISTRIBUTION IN CRYSTAL STRUCTURES
Korablin A.M., Ponamarev M.Y.
Abstract
The formation of the diffraction pattern during the passage of light beams, and Bessel Gauss-Laguerre through a plate of crystal quartz. Experimental studies of the differences shown in the formation of images and detect changes in the structure of the symmetric beams, depending on the orientation of the crystal plate. The proposed experiment allows us to see the benefits of the structural beams to the Gauss-Laguerre Bessel beams in the diffraction pattern as it passes through the crystal. The results are important for studying the mechanisms of diffraction of light beams in natural crystals and the development of new methods for determining optical parameters of crystal quartz.

NEURO-FUZZY CONTROL SYSTEM FOR TEMPERATURE CONTROL FERMENTATION
Lubentsova E.V., Volodin A.A., Lubentsov V.F.
Abstract
The algorithm of management on the basis of indistinct logic is worked out developed and the system of automatic stabilization of temperature of process of a fermentation in the bio-reactor of continuous action is investigated. Results of modeling of the fuzzy controller and assessment of its efficiency in comparison with the traditional proportional and integrated and differential regulator (PID-regulator) are given. For development of the regulator of stabilization of temperature of exothermic process of a fermentation the hybrid technology of adaptive neuro and indistinct system of the conclusions - ANFIS is used. The developed indistinct regulator provides requirements to stabilization of temperature of fermentative system at restriction on operating influence. Results of researches showed that introduction of the offered system will allow to increase the accuracy of maintenance of the set temperature concerning the PID-regulator for 2,1% and to cut a peak expense of a coolant on 43%. The robastnost to indignations on temperature of cooling water and compensation of a thermal emission of process at restriction on a consumption of cooling water is thus provided and at admissible temperature mismatches in system at a peak thermal emission.

IMPLEMENTATION OF METHOD OF FORMING SIGNALS WITH VARIABILITY FREQUENCY PROPERTIES ON PLATFORM NI PXIE-1065
Zhilyakov E.G., Belov S.P., Pashintsev V.P., Starovoit I.A., Ushakov D.I.
Abstract
The article discusses a hardware implementation of the method of forming the channel signals with variability frequency properties. This method is implemented on the platform of PXIe-1065 National Instruments. The implementation of this method makes it possible to generate signals that lack energy at predetermined frequency intervals, thus increasing data transmission immunity in conditions of concentrated interference spectrum.
