Method for limiting the peak factor using an additional compensation signal in a system with orthogonal frequency division multiplexing for a Gaussian channel
Authors: Pham Th. T. , Tikhonova O. V. 
Published: October 2024

Objectives.Orthogonal frequency division multiplexing (OFDM) has become the standard for various high-speed wireless communication systems due to its several advantages, one of which is the efficient use of bandwidth. The main disadvantage of OFDM is the high peak-power-to-average-power ratio (PAPR), which is indicated by an increase in the bit error rate due to the nonlinearity of the power amplifier. The paper sets out to evaluate the possibility of reducing the PAPR value using a limitation method developed by the authors involving an additional compensation signal in a channel with white Gaussian noise, as well as to analyze its main parameters.Methods.Statistical radio engineering and computer modeling methods are used according to optimal signal reception theory.Results.The effect of the OFDM signal limitation level and the number of additional signals when using the limitation method with an additional compensation signal on the quality (reduction of transmission losses) of the OFDM signal is analyzed. The results show a decrease in the OFDM signal PAPR value, along with the dependencies of the bit error rate on the signal-to-noise ratio at fixed limitation values and a determined number of additional signals in the channel with white Gaussian noise.Conclusions.The proposed limitation method with an additional signal when transmitting an OFDM signal in a channel with white Gaussian noise provides compensation for information losses due to signal level limitations in the transmission channel. Increasing the limitation level is shown to increase the PAPR value, while varying the number of additional signals changes PAPR insignificantly. In order to ensure the effective implementation of the limitation method with an additional compensation signal, the parameters of the threshold limitation level and number of additional signals should be selected depending on the predicted signal-to-noise ratio in the system.

Published: October 2024

Objectives. The retrieval of legal information, including information related to issues such as punishment for crimes and felonies, represents a challenging task. The approach proposed in the article represents an efficient way to automate the retrieval of legal information without requiring a large amount of labeled data or consuming significant computational resources. The work set out to analyze the feasibility of a document retrieval approach in the context of Arabic legal texts using natural language processing and unsupervised clustering techniques.Methods. The Topic-to-Vector (Top2Vec) topic modeling algorithm for generating document embeddings based on semantic context is used to cluster Arabic legal texts into relevant topics. We also used the HDBSCAN densitybased clustering algorithm to identify subtopics within each cluster. Challenges of working with Arabic legal text, such as morphological complexity, ambiguity, and a lack of standardized terminology, are addressed by means of a proposed preprocessing pipeline that includes tokenization, normalization, stemming, and stop-word removal.Results. The results of the evaluation of the approach using a dataset of legal texts in Arabic based on keywords demonstrated its superior effectiveness in terms of accuracy and memorability. The proposed approach provides 87% accuracy and 80% completeness. This circumstance can significantly improve the search for legal documents, making the process faster and more accurate.Conclusions. Our findings suggest that this approach can be a valuable tool for legal professionals and researchers to navigate the complex landscape of Arabic legal information to improve efficiency and accuracy in legal information retrieval.
Service quality assessment in IT projects based on aggregate indicators
Authors: Krasnov A. E. , Sapogov A. A. 
Published: October 2024

Objectives. Due to the need for prompt and rational assessment of service quality within the framework of complex IT projects, including infrastructure servicing and maintenance, which often involve a large number of identical or similar iterations, it becomes necessary to develop novel analysis methods based on nonlinear aggregation of indicators. As a result of changes in the structure of the process, territorial remoteness, automation, informatization, and the emergence of big data, the use of existing assessment methods often becomes impossible or labor-intensive. The purpose of the present work is to develop an approach to assessing the quality of work (services) in the framework of IT projects based on nonlinear aggregation of indicators.Methods. The proposed approach to assessing service quality within IT projects is based on nonlinear aggregation of a number of indicators involving a preliminary decomposition of the system into private indicators. In order to meet the requirements of the decomposition process, service quality indicators must fully characterize the properties of the service as a whole at the different stages of its life cycle.Results. The application of the proposed nonlinear aggregation methodology to quality indicators obtained by decomposing the system is described with the further calculation of a single indicator that takes all the essential initial parametric indicators into account. The decomposition of complex systems to the level of elementary relationship subsystems more adequately reflects interrelated phenomena in a complex system.Conclusions. The practical application of the neural network parametric data aggregation model for assessing the quality of IT services is demonstrated. The use of an aggregated information and analytical indicator for assessing service quality increases the availability of analytical information for decision makers, reduces the dimension of analytical data, and improves the objectivity of the obtained generalized information.
Effect of surface electromagnetic wave treatment on the refractive properties of thin films based on indium tin oxides with laser-deposited single-walled carbon nanotubes
Authors: Toikka A. S. , Kamanina N. V. 
Published: October 2024

Objectives. The article investigates the effect of surface electromagnetic wave (SEW) treatment on the refractive properties of thin conducting films based on indium tin oxide (ITO) with laser-deposited single-walled carbon nanotubes (CNTs). The effective thickness of the layer of laser-deposited CNTs before and after SEW treatment is evaluated.Methods. A laser-oriented deposition method employing a CO2 laser (λ = 10.6 µm) was used to form the structures. Diagnostics of modifications of ITO thin films were carried out using an ellipsometer operating in the spectral range of 300–1000 nm. The Cauchy model was used to describe the optical properties of K8 crown substrates and ITO thin films. To interpret the ellipsometry results of ITO modifications with CNTs, an effective-thickness virtual layer model was introduced. During post-processing of the surface, a CO2 marker (λ = 10.6 µm) was used to generate SEW. The influence of SEW treatment on the thickness of the virtual layer was assessed using ellipsometry and atomic force microscopy in contact mode.Results. Based on the ellipsometry data, the effective thickness of the CNT layer was in the range of 24–26 nm. Following SEW treatment, the thickness of the effective CNT layer decreased to 4–8 nm, indicating the possibility of precision processing of the ITO surface with CNTs using SEW. When CNTs are deposited on an ITO surface with subsequent SEW treatment of the surface, reflection losses for p-polarized radiation are reduced. In a spectral range of 400–750 nm at an angle of incidence relative to the normal to the plane of structures α = 65°, a decrease in reflection is observed from 18.5% to 13.5% relative to ITO without CNTs and SEV treatment; at α = 71°, a decrease from 6.4% to 4.7% is observed; at α = 77°, a decrease from 1.8% to 1.2%.Conclusions. For ITO-based thin films with laser-deposited CNTs, the described SEW treatment method provides a precise reduction in the thickness of the composite structure while preserving the antireflective properties of the CNTs. These capabilities make it possible to use the studied ITO modifications in solving problems in optical electronics, microfluidics, and biomedicine.
