UAV-assisted underlay CR-NOMA network: performance analysis

Dinh-Thuan Do, Chi-Bao Le

Abstract


We highlight the potential of non-orthogonal multiple access (NOMA) integration with
unmanned aerial vehicle (UAV) for future communications networks in beyond 5 gen-
eration (B5G) networks to enhance cellular communication, support massive connec-
tionsandincreasedatarates.Weconsiderascenario,whereaUAVcommunicates
in a downlink underlay cognitive radio based NOMA network (CR-NOMA) with two
destination users, a cellular device, and a primary destination following Nakagami-m
fading distribution.We study the impact of perfect and imperfect successive interfer-
ence cancellation (SIC) on outage probability (OP). To help analyze this impact,we
derive exact outage results for different network users under perfect and imperfect SIC
conditions.Consequently,wemakeuseofMonteCarlosimulationstoconfirmthe
analytical results.
