The modeling and investigation of nonlinear digital devices of selective supression of masking multidimensional pseudo-random signals of controlled discrete-nonlinear Chua and Lorentz systems are carried out. The effects of changing the temporal discretization parameters of the masking signals on the selective suppression coefficients of pseudo-random signals of controlled discrete-nonlinear Chua and Lorentz systems are investigated. The comparative estimates of the nonlinear transformation of the phase-shift keyed signals in devices for selective rejection of masking pseudo-random signals of controlled discrete-nonlinear Chua and Lorentz systems with dynamic chaos are obtained.

The most important part of any information transmission system based on dynamic chaos is a chaotic oscillator. The paper deals with issues of construction and gives a comparative analysis of two chaotic oscillators: one on time delay integrators and another one with the inertial circuit of the second order with a frequency-independent shaper in the feedback circuit. The simulations developed in PSIM-9 allow to do research of various types of generated chaotic oscillations reliant on changes in control parameters.

A combined algorithm for joint estimation the distortions of the OFDM signal and channel factors is proposed in the article. The algorithm is based on two procedures: 1) estimating the generalized channel factors using a polynomial spline approximation, the least squares method and finding the signal distortion estimates for them, 2) a nonlinear filtering algorithm to refine the parameters values such as DC components and frequency offset. The algorithm operates on two reference OFDM symbols under conditions of a priori uncertainty regarding phase noise and observation noise, and also allows to increase noise immunity and reduce computational complexity, as compared with the case of using only procedure 1).

This paper discusses an important component of the radio frequency identification (RFID) system, namely, the RFID-tag and the bending effect on its electrodynamic parameters. The RFID tag was modeled and the following parameters were calculated: Scattering Coefficients (parameter S11), Voltage Standing Wave Ratio (VSWR), vertical and horizontal radiation patterns and total. The results of the work will allow optimizing the design of the RFID-tag in such a way as to achieve optimal quantitative indicators of electrodynamic parameters.

The research performs an analysis of the communication link quality for the multiantenna system in terms of ergodic channel capacity and its higher-order statistics: fading figure, skewness, kurtosis, which are closely related with the possible capacity/rate deterioration as a result of channel instantaneous fluctuations. To account most of the possible physical effects concerning signal propagation a generalized κ-μ shadowed fading channel model was assumed.

Synchronization of elements of distributed systems is a classic task in many industries and there are many options for its solution. In this paper, we propose a synchronization option for a data acquisition system based on clocks synchronized by signals from GPS and GLONASS navigation systems. The content of the work is the algorithm of automatic entry into synchronism of the separated nodes of the system during their initial switching on and restoration of synchronous operation during synchronization failures that do not lead to failure of the node equipment.

The priority purposes of the 5G network are increasing throughput and increasing spectral efficiency. For this purposes, a number of tools have been developed, the realization of which full potential is possible only if there is feedback from the User Equipment (UE) - Channel State Information (CSI). However, in conditions of fading in the radio channel, there is a problem of ensuring the relevance of the indicators included in the CSI for subsequent data transmission in downlink. This problem has the name of the CSI-Ageing or CSI-Outdating. There are a number of methods for compensating the CSI-Ageing. Today, the most effective method to minimize the impact of this effect is prediction. There are many developed algorithms and a lot of research on this topic. However, there are only a few complete reviews these algorithms. This paper has the main purpose of conducting such a review and analysis in order to identify the most promising algorithms for further research.

The paper is devoted to the creation of an algorithm for determining the parameters of the electrocardiosignal (ECS) QRS-complex. The ECS model is created, all elements of which have average values of parameters of real ECS. An algorithm is developed that determines the temporal position of the peaks of the QRS-complex, as well as its beginning and end. The work of the algorithm when applying white Gaussian noise on the ECS is investigated. According to the research results, an algorithm of noise smoothing was developed and applied. This algorithm is based on averaging the signal in a specially selected time interval.
