Multi-purpose communication system interruption performance prediction method, system and device based on unmanned aerial vehicle cooperation, and medium

A multi-purpose communication system interruption performance prediction method, system, device and medium based on unmanned aerial vehicle cooperation, and the method comprises the steps: dividing the whole communication transmission time T into two time slots by using a time distribution ratio alpha, the first time slot alphaT, sending a signal xs to an unmanned aerial vehicle relay node R by a source signal node S, and the second time slot (1-alpha) T, the unmanned aerial vehicle relay node R decodes the received signal xs and broadcasts and forwards the decoded signal xs to all destination nodes Di, and meanwhile, an internal eavesdropping node E eavesdrops messages broadcasted by the unmanned aerial vehicle relay node R, deduces the outage probability and the safety outage probability in the whole communication process and analyzes the performance of the multi-destination communication system; the system, the device and the medium are used for realizing the multi-purpose communication system interruption
