Detection and demodulation of signals with modulation indexes greater than one in radio monitoring of aviation radio communication
DOI 10.51955/2312-1327_2024_2_119
Abstract. Communication between an aircraft and ground services is the main means of organizing air traffic control and providing the safety and regularity of air transportation. In order to maintain the operability of radio communication channels is to perform radio monitoring. This article considers a radio monitoring algorithm. It makes possible to classify amplitude-modulated signals by modulation depth, to show the possibility of detection of overmodulated oscillations and to restore the initial information message with sufficient accuracy for its perception.
Key words: overmodulation, double-sideband suppressed carrier modulation, signal analysis, interference detection, cognitive radio, radio monitoring.
