In addition, the growth of the concept of Internet of Things (IoT) makes it necessary to revise quantitative estimates on the client base of communication networks. Therefore, there is a need for new networks, which would be able to support trillions of devices, and can satisfy requirements for a high degree of reliability, quality and for high data transmission rate.

Decoding and decision making models, methods and algorithms for elementary signals of receiving devices of distributed control systems elements. Purpose. Development, research and realization of soft decoding and decision making method for elementary signals (channel symbols) within receiving devices of distributed control systems elements based on the fuzzy logic fundamentals and methods. Methodology of research. The analysis of signals distortions by noise of different sources and forms is carried out in this paper. The «quasioptimum» receiving methods for taking account of distortions are analyzed. A condition of uncertainty often occurs at reception so it is difficult to correlate the distorted signal with any of the possible basic (transmitted) signals. The probability of the error at the same time considerably increases. The application of fuzzy sets and fuzzy logic math fundamentals for taking into account and the subsequent removal of uncertainty when decision making is offered. The elementary signals soft decoding (decision making) method based on the fuzzy sets theory and fuzzy logic methods is developed. The decision making device model with Fuzzy Logic Toolbox (MathWorks MatLab) for the offered decoding method application is developed and researched. The common block circuit of the elementary signals quasioptimum receiver is released and the algorithm of it's functioning is described. Research results. The formal description of elementary signals distortions is executed, the variables for decision making are entered. The decision making method of received symbol based fuzzy logic fundamentals is developed; input and output variables and their membership functions are defined; productional rules are formulated; defuzzyfication algorithm is offered. The common block circuit of receiving device is developed used offered decision making method for conclusion formations about received symbol. The simulation and research of the offered circuit is executed; the quantitative assessments of their functioning are received. Application. The offered decision making method based on fuzzy logic fundamentals is planned to be used within elementary signals decision making device. This device is the general node at the common block circuit of receiving device within distributed control systems elements. Conclusions. The researching of the developed receiving device model has shown that the decision making method provides a preset reliability indicators, assumes the computing complexity decreasing due to the arithmetic operations using and the possibility of decision making model parameters adaptation to the change of external conditions (change of error model parameters in a communication channel, increase in requirements to reliability, etc.). It allows to increase the efficiency and reliability of soft decoding applied algorithms.","PeriodicalId":372303,"journal":{"name":"2017 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SINKHROINFO)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116384291","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}

It should be noted that for effective photomixing the polarization, frequencies and phases of the optical beams introduced into the mixer must be constant, otherwise it is necessary to additionally use a complex system of phase synchronization. In connection with the complexity of such an implementation, variants based on the conversion of single-frequency and broadband laser radiation into two-frequency ones were investigated. The first of these is modulation and consists in the external modulation of single-frequency laser radiation in the electro-optical Mach-Zehnder modulator. The second one is broadband with the allocation of two wavelengths using two rectangular fiber Bragg gratings with a small difference in width.","PeriodicalId":372303,"journal":{"name":"2017 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SINKHROINFO)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128238597","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}

As an example, a method based on modification of existing STM32F303 MCU's I2C interface by introducing additional noise immunity with corrective codes, as well as creating mechanisms for multicasting and arbitration is proposed.

In this paper we propose a model derived by the Wiener orthogonalization method. The one important feature of this method is that the resulted output decomposition depends on the statistics of the input signal, and initially it was derived by Wiener in application to Brownian input. Thus, we first establish the derivation of Wiener decomposition for the band-limited Gaussian inputs, and next we generalize the results to some of the non-Gaussian cases. Using the computer simulation, we show that the property of the Wiener decomposition to discriminate uncorrelated components in the output of ND holds also for the considered type of non-Gaussian input. In the experimental part of this work we mainly focus on the memoryless nonlinearity but we also show how the results may be used to construct a reduced-complexity memory nonlinearity model. We compare convergence behavior of the adaptive parameter identification process using the proposed model and the standard power series model. The results show the major benefit in the convergence speed.","PeriodicalId":372303,"journal":{"name":"2017 Systems of Signal Synchronization, Generating and Processing in Telecommunications (SINKHROINFO)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126754291","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}
