description: Topic of the final qualification work: "Development of a test platform based on SDR to study the effectiveness of multi-frequency signals". This work is devoted to the implementation of the receiver/transmitter model of an OFDM signal of various types of phase-amplitude shift keying on SDR. SDR devices act as a receiver and transmitter, and information on them can be transmitted via wire or using antennas.Implemented software settings for SDR - devices, the formation of an ODFM signal in the time domain in the form of complex readings in the C ++ environment and algorithms for processing the received signal in Matlab. The 802.11a standard was chosen as the basis. Studies have been carried out to identify the suitability of SDR for the formation of a communication system through OFDM - a signal in conditions of real noise, frequency and phase deviations, during which noise immunity curves were obtained. These curves were compared with the theoretical values ââcorresponding to the OFDM signal under AWGN conditions. Based on the comparisons, conclusions were drawn.Studies have shown the effectiveness of SDR devices in transmitting data via an OFDM signal. The resulting model can also be used in further studies to improve the quality of communication, supplemented by the ability to work with SEFDM signals.
