Abstract

The article is devoted to the study of the use of software-controlled radio (SDR) in the context of the growing demand for wireless technologies and radio-electronic devices. It focuses on the problems of oversaturation of the radio spectrum, the need to automate the management of radio systems, security, the use of machine learning and AI, the integration of various systems, as well as economic benefits. The paper examines the SDR as a tool to address these challenges, particularly due to its ability to operate over a wide frequency range and the use of digital signal processing. The role of SDR in radio monitoring and its importance in identifying and eliminating sources of interference are also revealed.
The main attention is paid to the development of the algorithm for performing OFDM-modulation operations in the SDR of intelligent control systems of the radio emission data collection network. The proposed algorithm aims to optimize data transmission, reducing the transmission of redundant bits of information and promoting efficient use of the radio spectrum. The article describes in detail the architecture and functionality of SDR, including an analysis of the impact of OFDM technologies on the efficiency of data transmission within software-controlled systems.

Keywords: SDR, digital signal processor, radiomonitoring, intelligent system, OFDM, guard interval, modulation, algorithm.
