| Summary: | Unmanned aerial vehicles (UAVs) aided communication
has acquired research interest in many civilian and
military applications. The use of UAV as base stations and as
aerial relays to improve coverage of existing cellular networks is prevalent in current literature. Along with this, a few studies have proposed the use of non-orthogonal multiple access (NOMA) in UAV communications. In this paper, we propose a network where a ground user and an aerial UAV relay is accessed using NOMA, where the UAV acts as decode-and-forward (DF) relay to extend the coverage of source. The performance of the proposed
model is shown by evaluating outage behaviour for different
transmit power and fading environments with Monte Carlo
simulations. System throughput of proposed network appears to be better than orthogonal multiple access (OMA) based equivalent network. The results show that with an adequate height of the UAV NOMA based relay, quality of service (QoS) of cell edge user is satisfactory. |
