THE INVESTIGATION OF ERROR-CORRECTING CODING OF THE VARIOUS FILES

UDC 681.3

E. I. Vorobyev, Y. P. Preobrazhenskiy


Problems related to the protection of information from interference are relevant in a variety of practical applications. The information itself can be text, graphic, contain video clips. Interference can be unintentional as well as specially created by cyber criminals. To process and transmit information in practice, various noise-resistant codes are used. The paper discusses the characteristics of some similar stakes: Hamming code, code, reed-Muller, BCH code Bose-Chowdhury-Hoquinghem. The results of comparison of characteristics-correcting codes are shown. An illustration of the encoded text and those bits that have been distorted. A graphical dependency is given to illustrate the dependence of the number of corrected errors on the number of errors that were added to the original message for the three selected codes. The results of studies of the characteristics of redundancy of codes with different files are shown. The BCH and reed-Muller codes were chosen for testing. Txt, midi, wmv and mpeg-2 files were analyzed. A table on the results of research, which shows how the file size, as well as its appearance, have an impact on redundancy. It is established that Hamming and reed-Muller code fix single errors well, BCH code is suitable for correcting various errors.

Keywords: : coding, information, correcting ability, error.

MODEL OF DISTRIBUTION OF RESOURCES OF THE AUTOMATED MANAGEMENT SYSTEM OF MILITARY AND DOUBLE APPOINTMENT IN CONDITIONS OF INSUFFICIENCY OF INFORMATION ON DEVELOPMENT OF INTERFERENCE-TARGET SITUATION

UDC 623.618

D.O. Krikunov, V.A. Malyshev


The article considers the problem of resource allocation automated control system of military and dual-use in terms of lack of information about the development interference-target situation. The urgency of this problem caused by low quality of planning, allocation and utilization of resources of the automated system in terms of the lack of information about the development interference-target situation, which reduces the efficiency of the system itself and its application. The problem is solved by means of the developed model resource allocation system in terms of the possible appearance at the entrance to a variety of perturbations adapted to the current situation of the occurrence of armed conflict. The model is a representation of the solution of a vector optimization problem and construct the function a guaranteed win in the binary relationships of conflict, cooperation and indifference. Thus, solved the problem of resource allocation automated control system of military and dual-use in terms of lack of information about the development interference-target situation by means of creating a model of such a system taking into account the possibility of its entrance to a variety of disturbances. It also justifies the decomposition of the system, which allows to represent the solution of a vector optimization problem binary relations of conflict, cooperation and indifference. Proposed approaches to the construction of a utility function and a guaranteed win, and a numerical optimization scheme on this set.

INFORMATION TECHNOLOGY OF DISTRIBUTION RESOURCES OF THE AUTOMATED MANAGEMENT SYSTEM OF MILITARY AND DOUBLE APPOINTMENT IN CONDITIONS OF INSUFFICIENCY OF INFORMATION ON THE DEVELOPMENT OF INTERFERENCE-TARGET SITUATION

UDC 623.618

D.O. Krikunov, V.A. Malyshev

The article considers the information technology of resource allocation for an automated military and dual-use control system in conditions of insufficient information on the development of noise-target conditions. The unpredictability of future interference effects and the possible change in objectives, the insecurity of domestic resources, as well as other almost unpredictable impacts, are called disturbances. Information technology is represented by a structural model in the form of a tuple of models performing certain narrowly directed functions on interaction with disturbances. The first model, included in the tuple, is the information model of possible perturbations, the second model describes the connections of the set of disturbances to the input of the automated control system, the third model converts the input object (disturbance) into an output object (control action), the fourth describes the connection of the output of the automated system with the set of disturbances, and the fifth set of reactions of the automated system to the appearance of each perturbation. Based on the technology of resource allocation for an automated military and dual-purpose control system under conditions of insufficient information on the development of the noise-target situation, an algorithm for its implementation has been constructed, including the consecutive implementation of five phases. Dedicated models due to the invariance of system properties are applicable to the description of the process of resource management of an automated control system at all levels of its organization.

Keywords: resource allocation, models, information, technology, automation, control systems.
