Toward Performance Analysis and Trajectory Design for UAV-Enabled Covert Communication Under Nakagami- m Channel

IEEE Wireless Communications Letters, vol. 15, pp. 3009–3013

Abstract

In this letter, we focus on performance analysis and UAV trajectory design for UAV-enabled covert communication under Nakagami-mchannel which is still an open issue, where a joint segmentation ratio, UAV trajectory and transmit power design problem is formulated to maximize the minimal throughput under covertness constraint. To solve the complicated problem, the covert communication performance under Nakagami-mchannel is first analyzed where the monotonicity of the minimal detection error probability is utilized to reformulate the original problem into a simplified one. Then, an efficient iterative algorithm based on a novel convex approximation method is proposed to solve the non-convex problem efficiently. Finally, numerical results are provided to validate the proposed scheme.
