SIMULTANEOUS FILTRATION OF DISCRETE AND CONTINUOUS PARAMETERS OF THE MULTIDIMENSIONAL CORRELATED PULSE SIGNALS
Medvedeva E.V., Petrov E.P., Metelyov A.P.
Abstract
Synthesis of algorithms of simultaneous filtration of discrete and continuous parameters of multidimensional binary correlated signals is considered. It is supposed that all parameters are Markov processes. The simultaneous filtration of parameters is carried out with white Gaussian noise. The synthesized algorithms require for the realization of the minimal resources and allow to increase noise stability of reception of pulse signals.

MATHEMATICAL MODEL FOR RESEARCH OF PROPERTIES OF HIGHWAYS OF TRANSPORT NETWORKS AT USE OF SEVERAL CLASSES OF SERVICE
Gavlievskiy S.L.
Abstract
In this article was made the system of the nonlinear algebraic equations describing streams on branches and units of a network in a stationary mode at address dispatch of packages on a multiservice communication network with several classes of service. The decision of system allows to calculate for each grade of service time of a delay and probability of losses of packages between each pair units of a network, and also streams for branches and units of a network, a delay, probability of blocking and levels of loadings of channels. The example of calculation of characteristics of a highway of a multiservice network is given.

APPLICATION OF THE HUNGARIAN ALGORITHM AT THE DECISION OF PROBLEMS OF DISTRIBUTION OF TELECOMMUNICATION OPERATIONAL LIFES FOR LOCAL AREA NETWORKS ON MOBILE PLATFORMS
Averyanov Е.С., Kaseeva N.A., Nazarov S.N.
Abstract
In work principles of performance of a local area network of the subscribers placed on a mobile platform, carrying out relocating with a HS on a train example (mobile hotspot (MHS)) are analyzed. The present work is devoted developments of algorithms of boosting of efficiency of performance MHS on the basis of the decision of an optimizing problem of determination of the maximum transmission capacity of system. The problem decision is offered to be broken on two subtasks: determinations of set of conformity of repeaters of a base network and antennas on a mobile platform and distributions of power of a signal transmission on links from set of conformity. The decision of the first subtask is offered to carry out on the basis of the Hungarian method, the second - a simplex-method.

ISOLATION AND COMPARISON OF FEATURES POINTS ON THE IMAGES OF OBJECT
Alenin V.A., Kulyas O.L.
Abstract
Isolation points of interest (POI) and determination of their compliance are important components of many applications of computer vision. For example, in the algorithms of automatic alignment and alignment of images, construction («matching») composite mosaics and panoramas, the reconstruction of three-dimensional images, etc. By selecting and implementing a specific algorithm selection and compare features directly affects the speed and accuracy of the reconstruction algorithms. In this article analyzes existing methods of selection and comparing POI, and also is offered the new algorithm, allowing to increase an amount of true correspondences.

COMPUTER SIMULTION ELECTROMAGNETIC COMPATIBILITY OF 802.11g AND SYSTEMS WiMAX
Devitsyna S.N., Saharov A.I., Sidorenko I.A., Ushakov D.I.
Abstract
In the article considered evaluation of electromagnetic compatibility systems standards of 802.11g and 802.16-2004 by computer simulation. Because the OFDM signal has high levels of out-of-band emission is the presence of frequency spacing between the frequency ranges of systems Wi-Fi and WiMAX can not provide ensure a stable electromagnetic environment of these systems. . The paper also presents simulation results, which reflect the dependence of bit error probability of the distance between devices, WiFi and WiMAX at various distances from the base station of the latter.
