In view of the scarcity spectrum resources in wireless communication, it is studied this paper over two-hop cognitive secrecy transmission scheme decoding and forwarding (DF) unmanned aerial vehicles (UAVs) assisted relay with energy harvesting under Nakagami-m channel. It worth noting that terminal node equipped multiple antennas optimal antenna selection can be adopted for signal reception. Meanwhile, UAV uses time switching (TS) power splitting (PS) techniques adopts capacity scheme. successfully derived exact closed form expressions non-zero probability outage while eavesdropper has no channel state information (CSI). Moreover, system asymptotic demonstrates diversity order gains network Furthermore, joint optimization factor other parameters effectively increase improve performance. Simulation results verify correctness theoretical derivation effectiveness proposed scheme, which demonstrate algorithm outperforms compared schemes.
