摘要：
In this paper, a joint wiretap and covert transmission method is proposed for uplink multi-user multi-antenna ground to unmanned aerial vehicle (UAV) communications. To characterize the fundamental limit of the above scenario, we formulate an optimization problem to maximize the sum of secret and covert transmission rates subject to constraints of secrecy outage probability (SOP), detection error probability (DEP), and the transmit powers of secret and covert transmitters. To solve the optimization problem, we propose a bisection search algorithm using semidefinite relaxation and reveal the influence of key parameters on the wiretap and covert transmission rates, analytically and numerically. Our results fill the gaps in joint wiretap and covert transmission for uplink multi-user multi-antenna UAV communications and provide new insights to construct such systems.
