The presented research analyzes the energy-based detection (ED) problem of a signal propagating in a wireless severely fading channel. To account for the worst-case propagation conditions, the newly presented for wireless communications Lomax channel model (exhibiting the hyper-Rayleigh conditions for all the possible parameters’ range) was used. The system performance was characterized by the average probability of detection, receiver operating characteristic (ROC), and the area under the receiver operating characteristic curve (AUC), that were studied as the functions of the system and the channel parameters (i.e., the sensing base, the average signal-to-noise ratio (SNR), and the SNR probability distribution function scale parameter). The results of the numerical simulation were analyzed in comparison with the existing regulation implied by the 5G NR standard on the ED for medium access procedure. ©2024 IEEE.

The paper investigates non-recurrent algorithms for obtaining soft solutions for a four-position quadrature amplitude modulation (4-QAM) signal in conditions of estimating communication channel parameters with different accuracy in a communication system with multiple transmitting and receiving antennas (MIMO). The communication channel was modeled using the Jakes model, which takes into account Doppler spreading and Rayleigh fading of the signal. The additive noise was assumed to be white Gaussian. The channel matrix takes into account the distortions received by the signal in the direct conversion receiver path, such as amplitude and phase imbalance between signal quadratures, phase noise, frequency shift remaining after the demodulation procedure, and DC components. The noise immunity of the proposed regularizing procedures was compared with the known algorithms Zero Forsing, minimum mean square error (MSE) and a procedure based on the least squares method (LSM) for a MIMO system with a number of antennas of 8, 16, 32 and 64. The computational experiment showed that that a regularizing algorithm for finding soft solutions can provide an energy gain in noise immunity with inaccurately known parameters of the communication channel relative to other signal detection procedures considered in this work. ©2024 IEEE.

Increasing truck loads, expanding transportation processes, and expanding intermodal transportation are exacerbating the impact on road surfaces. Organizations involved in cargo transportation are faced with the need to find effective solutions to optimize processes and select transport, taking into account legal restrictions. The use of automated decision-making systems based on aggregated big-data from telematic control systems is the best practice. The authors consider the problems of implementing systems for estimating mass, load and degree of body loading. Based on data on cost and potential harm to the road, a multicriteria optimization problem is solved to select the optimal transport model. The modified method of searching for Pareto-optimal solutions is used as a mathematical method. The results of experimental studies of the influence of transportation process parameters on the load capacity utilization rate are presented. The resulting mathematical optimization model is ready for integration into automated cargo transportation management systems and has a calculation error of up to 12.8%. ©2024 IEEE.

despite the widespread development of satellite mobile communications, radio communications in the high frequency range (3 - 30 MHz) retains its position when it is necessary to ensure over-the-horizon data transmission with low delays. The transmission speed of samples from the world's leading manufacturers reaches 120 kbit/s with a used radio channel width of 24 kHz. Manpack radios place high demands on weight and size characteristics, which are largely determined by the efficiency of the most energy-intensive unit - the power amplifier (PA). The article analyzes ways to increase the PA efficiency taking into account the features of modern telecommunication signals that use amplitude-phase modulation and have a large crest factor. Based on a preliminary analysis of a wide range of directions for increasing the radio frequency amplifiers efficiency, the most promising options for the problem under consideration are selected: a power amplifier with envelope elimination and restoration (EER) and an amplifier using the outphasing method. To date, the theoretical issues of constructing the EER PA and the prospects for its practical implementation have been better developed. At the same time, the potential capabilities of a transmitter built using the outphasing method are higher than those of the EER PA, since it does not have an inertial low-frequency envelope path, which reduces both energy performance and limits the possibility of improving quality characteristics. A conclusion is made about the advisability of further research, modeling, prototyping and testing of the transmitter using the outphasing method. ©2024 IEEE.

The article is devoted to the development of signal-code structures (SCC) for low-energy broadband radio links. The SCC is based on multi-frequency signals with a continuous phase (M-Cpfsk) and non-binary error-correcting codes (Non-binary low-density parity-check and turbo-like). An analysis is made of signal-code structures for bands up to 10 MHz with different parameters. These signal-code structures can be used for command-telemetry radio links from unmanned aerial vehicle (UAVs). © 2023 IEEE.

In the era of development of telecommunication technologies, triple-play services via IP networks in real time are of considerable interest both for operators of transport and on-board systems, and for consumers of services. One of the characteristic features of real-time applications is their sensitivity to delays and data packet losses. Even small packet transmission failures can lead to a significant decrease in the quality of audio and video programs. All this imposes additional requirements on operators of transport and on-board systems delivering audio and video streams to content providers, which should be taken into account in their SLA agreements. The article discusses the requirements for IP network operators to deliver audio and video streams with proper quality, and provides an approach to evaluating the operator's performance when switching to SLA work. © 2023 IEEE.

The development and use of on-board photovoltaic panels (PVP) makes it possible to improve the energy supply of unmanned or manned aerial vehicles, which are respectively positioned, for example, as flying base stations or vehicles with on-board batteries with a large energy reserve, capable of carrying more payload during long flights. The efficiency of a photovoltaic element (PVE) is seriously affected by clouds, blocking solar radiation, possible contamination or precipitation accumulated on its protective coating, aging of the PVE material, and the most important parameter – temperature. The aging effects and to a greater extent their temperature, affect the current-voltage characteristics of the PVE, so an on-board measurement system for its performance parameters can provide valuable information for optimizing the power generation process. The article proposes a methodology for monitoring the temperature of PVE and PVP in whole, which provides determination of their temperature over an area based on networks of fiber-optic sensors (FOS) and their addressed interrogation using a microwave-photonic approach. ©2024 IEEE.

In this paper we discuss the problem of dynamic measurements of digital measuring device for on-board radio electronic equipment. For such a measuring device, when a moving object moves under conditions of influencing noise, the accuracy of measurements decreases. The problem of increasing the accuracy of such dynamic measurements is considered. This article proposes the method for increasing accuracy for on-board radio electronic digital device applied at the moving object with on-board electronic equipment. Theoretical consideration of the accuracy of navigational determinations of the onboard measuring device under noise conditions and taking into account the object's movement dynamics is carried out. The article provides a theoretical analysis and computer simulation of the considered digital measuring device for on-board radio electronic equipment. It has been found that when combining on-board navigation and radio communication facilities are usually used to improve the accuracy of navigation determinations by implementing differential operating modes, it is possible to improve the accuracy of dynamic measurements. © 2023 IEEE.
