Title: Principles and Technologies of Digital Communication Based on Software Defined Radio: A Review of Modern Trends in the Field of Creating a Curricculum
Abstract:Current trends in software-defined radio (SDR) penetration into science, production and education is determined by the appearance on the market of affordable and multifunctional software and hardware ...Current trends in software-defined radio (SDR) penetration into science, production and education is determined by the appearance on the market of affordable and multifunctional software and hardware solutions. Analysis of the experience of a number of foreign universities suggests a new educational paradigm in the field of telecommunications and radio communications related to the direction of the SDR. From an educational point of view, the field of the SDR is interdisciplinary and covers the following courses: radio receiving and radio transmitting devices, digital signal processing, theory of electrical communication, programming and simulation modeling. The integrating role of the SDR course is to develop a system approach for analyzing and synthesizing a modern transceiver with the ability to programmatically implement most of the functions of the physical layer and with final approbation of its work in real field conditions. The purpose of this work is to review current trends in the creation of a curriculum for training specialists in the course "Principles and Technologies of Digital Communication Based on Software Defined Radio". Thus the work analyzes architecture and evolution of the SDR radio station, current trends and foreign experience in the use of SDR in education, the hardware structure of the radio receiver RTL-SDR, features of the implementation of the SDR transceiver in open source software. To assess the performance indicators of the SDR transceivers, the conclusion contains approach for half-natural experiment testing on the Keysight test bench.Read More
