UAV; SNR; outage probability; detection performance; secure concealment rate.Abstract
Recently, Unmanned Aerial Vehicle (UAV) as a flexible platform has received extensive attention from scholars at home and abroad. Compared with terrestrial communication, UAV has the unique advantages of high flexibility, wide coverage and no influence of terrain. In this paper, two aspects of UAV outage probability and covert communication are discussed and two system models are established, respectively. In the first aspect, the outage probability expression is calculated using the output SNR, and then the relay drone’s best position is solved in order to minimum outage probability. In the second aspect, in the case of the presence of listener and eavesdropper in the system, the detection performance of the listener is discussed, and then the secure concealment rate of the system is analyzed.
