ABOUT THE CHOICE OF THE IRREDUCIBLE POLYNOMIALS FOR THE SEA ALGORITHM
Babenko M.G., Chervyakov N.I., Babenko M.G., Chervaykov N.I.
Abstract
The SEA algorithm for fi nding the number of points of an elliptic curve defi ned over a prime fi eld is analyzed in the article. In the case of «prime Atkin» is proposed to construct quadratic fi elds, the authors recommend the use of irreducible binomials, which allow the most effi cient to implement arithmetic in quadratic Galois fi eld.

THE PROBLEM OF THE SYNTHESIS OF OPTIMUM BASIC STATIONSNETWORK STRUCTURE
Kontorovich T.A., Os'makova A.G., Kontorovich T.A., Osmakova A.G.
Abstract
Hereby substantial statement of a problem of synthesis of optimum network structure is given and a definition of optimum network structure is formulated. Criteria of an optimality, restrictions and conditions at which the solution of the stated problem and mathematical model of the problem of the synthesis of optimum network structure are possible are also offered. Formal-heuristic method of the optimum network structure synthesis of the GSM of new generation is offered as well. Results of the latest experimental check confi rmed the assumption that the planning of variants of structure of a cellular network with use of the offered method of the synthesis promotes construction of the variants demanding smaller expenses.

APPLICATION OF BROADBAND SIGNALS AT THE REMOTE MANAGEMENT OF THE RADIO SET ON LONG DISTANCE CHANNELS
Nazarov S.N., Pyatakov A.I., Nazarov S.N., Pjatakov A.I.
Abstract
In work ways of the decision of a problem of shortage of transmission capacity to radio networks of a decameter range, including military-oriented are analyzed. The present work is devoted development of algorithm of performance of the adaptive radio communication systems with simultaneous transmission to one channel of reports of information and control instructions mode of operations a radio set, and also a procedure of an estimation of parameters broadband the signals used for carrying over of control instructions. It is offered, for magnifying of transmission capacity of the channel, a service information operating mode of operations by a radio set to transmit not mixed up with information blocks, and simultaneously, in a common strip of the channel. For service information carrying over to use broadband signals.

Ivanov A.I., Mayorov A.V., Nadeev D.N., Funtikov V.A., Ivanov A.I., Mayorov A.V., Nadeev D.N., Funtikov V.A.
Abstract
It is shown, that changing entropy of natural and synthetic languages function is unambiguously concerned with parameters of hi-dimension correlation matrix of random code chains. For any natural or synthetic languages can be constructed the generator of random sequences reproducing sorting pair-correlation matrix of language and its exponent of lowering entropy, when spectator dimension is growth.
