Abstract

A fixed UAV-assisted decode-and-forward relay network is examined from the perspective of physical-layer security under residual transceiver distortion. The source communicates with the destination only through the UAV relay, and the eavesdropper overhears the relay transmission. Independent Nakagami-m fading is used for the three wireless links so that different UAV propagation conditions can be represented within one model. Based on the SNDRs of the two legitimate hops and the wiretap hop, expressions for SOP and SPSC are derived, and simplified finite-sum integral forms are given for integer fading parameters. The numerical study confirms the analytical results and shows how fading severity, secrecy-rate demand, eavesdropper SNR, and impairment level affect secure transmission.
