Abstract
The outdated relay selection algorithm for UAV-enabled cooperative amplify-and-forward NOMA networks is investigated in this paper. The impacts of the system parameters such as the outdated coefficient, the transmission SNR, the relays’ number and the average channel gain are evaluated by the exact analytical expressions as well as the asymptotic results on the outage probability. Based on the asymptotic expressions, we find that the diversity order of the system remains one, regardless of the relays’ number and the average channel gain. Simulation results are provided to confirm the theoretical analysis.
