The article discusses issues related to the development and implementation of a distributed computing system that makes it possible to simulate and analyze multiple experiments for data transmission in the case of using multi-frequency communication sys-tems. Signal models with maximum entropy are used as message source models. As a model of a communication channel with noise, a channel with additive Gaussian noise which has a uniform spectrum in a given frequency band is used. The implemented computing system allows tabular and visual analysis of such parameters of the multiple experiments as the number of signal subcarriers, the range of time interval for signal restoration, the signal-to-noise ratio, the quadrature and in-phase components of the QAM signal, the energy and information characteristics of the signal and the speed of data transmission of the communication channel. The results of the serial experiments are illustrated in form of interactive graphs with animated effects.","PeriodicalId":508406,"journal":{"name":"Infokommunikacionnye tehnologii","volume":"16 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140495079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two generators developed on the basis of the Lorentz system with chaotic dynamics are considered. The first generator is described by the Lorentz system implemented over a Galois field, and the second is described by the Lorentz system in which digital sequence formation occurs by periodic sampling from signal signatures. As an additional confirmation of the relevance of the results obtained, the article valuates a generator developed on the basis of the standard Matlab function for binary random sequence generating. Generator testing was carried out using a test battery developed by the National Institute of Standards and Technology, which includes 15 different tests. The results obtained are compared with the results obtained by testing reference generators. The results of this research can be applied in the development of cryptographic and data transmission systems.","PeriodicalId":508406,"journal":{"name":"Infokommunikacionnye tehnologii","volume":"21 11-12","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140496199","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A study on the use of various fuzzy functions in solving the problem of approximation of probability densities was carried out. Experiments were conducted on time series with preset distribution laws, evaluating approximation quality using standard deviation in the series of 29 tests. As a result of the research, using Gaussian fuzzy function, the mean value of standard deviation equal to 0.00145 determined which confirms good approximative ability of the fuzzy perсeptron. The system was tested on the acceptance test data of the gas compressor engine. In this case, approximation quality was assessed using the Kolmogorov-Smirnov agreement criterion.

By the way no attention is paid to reading tolerance in steganography, since it is believed that this issue is solved by preliminary crypto-graphic encryption of the message.
