Development of Signal Detection and Recognition Algorithm Using Software-Defined Radio

The article presents an analysis of the existing algorithms used in the implementation of a receiver of multi-position signals based on SDR technology. As a result, a comprehensive approach has been developed to solve the extended task of radio monitoring, which includes not only scanning the spectrum, detecting radio emissions, determining the type of modulation and the location of the source, but also decoding the data contained in the message. To implement the SDR-based algorithm, the GNU Radio program was used, which is convenient because it allows you to build circuits using software modules.
