UAV-Enabled Covert Communication With Movable Antenna Against Cooperative Detection

IEEE Transactions on Vehicular Technology, vol. 75, pp. 15299–15304

Abstract

In this work, we focus on an uncrewed aerial vehicle (UAV)-enabled covert communication with movable antenna against cooperative detection, which is still an unexplored issue. The covertness performance is first analyzed with the consideration of cooperative detection mechanism among wardens. Then, a joint design problem of segmentation ratio, transmit beamforming, trajectory and antenna position is formulated to maximize the minimal throughput among users while adhering the covertness constraint, which is extremely hard to be tackled due to the coupled variables and non-convex format. To address the problem, we develop an efficient iterative algorithm based on block coordinate descent (BCD) scheme and a novel convex approximation method, which converges to a high-quality solution efficiently. Finally, numerical results validate the benefits of our proposed scheme with respect to benchmarks.
