Abstract

Currently, various applications of ultra-wideband signal–code constructions are among the most vibrant technologies, being implemented in very different fields. The purpose of this research consists of analyzing Barker codes and searching for the optimal nested representations of them. We also aim to synthesize signal–code constructions based on the tenets of nesting of alternative modified Barker codes, which employ an asymmetric alphabet. The scientific merit of the paper is as follows: on the basis of new analytic expressions, modified nested codes and signal–code constructions were obtained, applicable for the establishment of the unambiguous association of the component values of the nested codes with any lobes of the normalized autocorrelation function. With these analytical expressions, we are, hence, able to determine the values of the binary asymmetrical components of the nested codes related to the side lobes of the normalized autocorrelation function. In this way, we clearly obtain better (low) levels for these lobes than by using the autocorrelation function, as established by the equivalent conventional Barker codes, including the nested constructions. Practical application of these modulated ultra-wideband signals ensures improved correlational features, high-fidelity probabilistic detection, and more precise positional detection of physical bodies depending on the range coordinate.

Abstract

Biotelemetry, or medical telemetry is being developed more and more recently. Biotelemetry has enormous opportunities to make health care more efficient and safe while reducing costs. However, the currently existing implantable devices must be periodically removed from the body of the object of observation to replace the source of energy, and then re-install into the body. Power sources have become the main limiting factor for increasing the life of the implant. They are an obstacle to the further miniaturization of implantable devices. The development and further application of this work will lead to a significant improvement in the use of implantable medical devices, thanks to the improvement of a number of indicators, including those associated with charging an implantable device. Analysis results of similar works and predictive research in the field of energy supply of implanted devices, the most efficient and safe method to reduce the battery recharge time suggests the use of pulsed current or pulsed voltage.

Abstract

A technique has been developed for experimental verification of software that implements the algorithm for graphematic analysis and preprocessing of text resources. This software is used to solve the problem of automated mining analysis of poorly structured data. It is designed to extract semantically significant constructs from poorly structured resources, which is achieved by transforming text using a number of auxiliary algorithms and classifying the data obtained using machine learning algorithms in Python. At the first stage of the developed algorithm, abbreviations and acronyms are searched in a text file. After searching for abbreviations and acronyms using templates, a search is performed for graphematic descriptors, namely name, email and URL, phone number and date. At the final stage of the developed algorithm, the boundaries of sentences and direct speech are distinguished. [ABSTRACT FROM AUTHOR]

RELIABILITY of telecommunication, STRUCTURAL reliability
Abstract

Complex indicators of reliability of telecommunication systems and communication networks are considered. The upper bound of the structural reliability of the communication network has been determined. The reliability of a communication network with limited bandwidth of communication channels is evaluated. A method for determining the connectivity of a communication network has been developed. The indicators of the reliability of the communication network are determined. [ABSTRACT FROM AUTHOR]

Abstract

Methods for determining the linear spectral frequencies using the properties of the divided differences' scheme and the modified Newton method have been developed. The proposed methods are based on the adaptation of several existing algorithms for calculating the linear spectral frequencies. The best choices are algorithms that offer a trade-off between precision and computational complexity. Frequency determination accuracy is independent of each other and can be adjusted. The results obtained can be used to analyze the efficiency of determining the convergence and the complexity of calculating the linear spectral frequencies. [ABSTRACT FROM AUTHOR]
