systems of signals generating and processing in the field of on board communications

作者： E. O. Kandaurova D. S. Chirov Moscow Technical University of Communications and Informatics Moscow Russia

This article discusses the issues of practical implementation of the previously developed algorithms for intelligent tuning of operating frequencies in cognitive radio systems. Two SDR devices of the LimeSDR type were used as a model of the cognitive radio system. An OFDM signal with an adaptive signal-code structure is used as a system signal. Service information about the parameters of the signal-code structure and the number of the frequency channel of the next frame is transmitted in the pilot signal subcarriers. To implement the algorithm, special software has been developed. Experimental studies were carried out with the use of software, where it was shown that the use of an algorithm for predicting the occupancy of frequency channels can reduce the time of operational scanning of the spectrum.

systems of signals generating and processing in the field of on board communications

作者： N. Yu. Liberovskiy D. S. Chirov V. S. Priputin Moscow Technical University of Communications and Informatics Moscow Russia

This paper investigates the effectiveness of the blind signal separation algorithm in the problem of detecting digital BPSK signals. The classical methods of blind separation of signals and criteria for signal independence are considered. A model of the studied algorithm for blind signal separation is shown, based on the calculation of a mixing matrix that brings the joint cumulants of the second and fourth orders to zero. To exclude a trivial solution, additional restrictions are imposed on signal dispersions. A system of equations for finding the mixing matrix coefficients is presented. The form of the coefficients of the mixing matrix is shown, which brings the signals to an uncorrelated form. The possibility of an analytical solution of the equation associated with the equality of the joint fourth-order cumulant to zero is shown. A model of modulation and detection of digital signals is described. The simulation result of the blind signal separation algorithm is presented graphically. The efficiency of the proposed algorithm is shown.

This article proposes solution for analyzing road safety level on sections of road network (RN) using geographic information systems as part of intelligent transport systems (ITS). Namely, one of DCRE (Driver-Car-Road-Environment) system components - “road”, and its impact on traffic safety, were studied in detail, and solutions for identifying typical sections in geoinformation systems (GIS) were presented. Various factors affecting road safety, accident likelihood and severity of their consequences are considered, depending on hazardous areas location (in settlements and beyond).

The object of consideration is design automation and prototyping of complex signals and their generation and processing devices. The subject of the analysis is the substantiation of the structure, composition and implementation method of a modeling system aimed at modeling and prototyping promising devices for the generation and processing of complex signals based on fast transformations in Galois fields. The purpose of the analysis is a reasonable choice of methods and tools for computational, simulation and prototyping that achieve high display accuracy, performance, flexibility and ease of modeling. The solutions are based on the principles and mathematical models developed by the authors: methods and algorithms for fast transformations in Galois fields, an algebraic representation model and the structure of fast delay acquisition devices for a subclass of sequences. The article is devoted to the development of a software and hardware modeling systems that allows the most accurate mapping of fast algebraic transformations in Galois fields to algorithmic models of various levels of representation to ensure high performance, flexibility and ease of modeling, as well as prototyping of promising devices for the generation and processing of complex signals. The results of the work will be useful in the design of promising devices of various information and communication systems, scientific research, as well as in the educational process.

Network modernization using software-defined networks (SDN) technology and network functions virtualization (NFV) involves the use of a unified physical infrastructure, based on which various applications that implement all possible network functions operate. The explosive growth of mobile devices and content, as well as virtualization and the emergence of cloud services, is forcing the network industry to rethink traditional architectures. In networks with SDN architecture, the network industry is actively developing OpenFlow Protocol to provide communication between the control layer (SDN controllers) and data transfer devices (SDN switches). This article offers possibilities for modernization optical networks using various options for implementing SDN/NFV technologies.

The susceptibility of distortions introduced by compression from the point of view of human perception is an important area of research. The ultimate purpose of video quality assessment is to emulate the performance of the biological visual system. Perceptual distortion models have proven successful in describing spatial coding in all human visual systems. However, the question of how the visual regions of the human brain process temporal information have received significantly less attention. Based on the researches of limit to human vision, here we offer a method, software, and test equipment for research and measure the characteristics of human visual systems. This set forms and evaluates stimuli with a specified combination of spatial, temporal, and color characteristics, which differ in a narrowband enough spectrum for measurements.
