Robust UAV Communications with Jamming

Unmanned aerial vehicle (UAV) communication has attracted increasing attention recently, benefiting from its high mobility. However, most existing studies concentrate on a perfect scenario, without considering the unintentional interference/intentional jamming and uncertain channel/location information. In addition, the UAV-to-UAV (U2U) communication scenario has not been widely investigated as the UAV-to-Ground case. To fill this gap, this paper investigates the robust U2U communications in the presence of jamming, where the U2U communication channel and jammer location are considered to be uncertain, i.e., only having partial information. For the non-convex optimization with the aim of minimizing the flight time, we propose a successive convex approximation method by introducing S-procedure and slack variables. The inner optimization is transformed into a semidefinite programming problem, which can be optimally solved by standard convex techniques. Simulation results validate the proposed path planning method in the presence of jamming.
