Performance analysis of adaptive modulation in UAV relay networks with interference

Abstract

This paper investigates the performance of adaptive modulation in unmanned aerial vehicles (UAVs) relay networks, in order to enhance the utilization of the spectrum resources and ensure the stability of the signal transmission, the UAV relay with the best communication link is selected to transfer the information to the target node via the decoding and forwarding protocol. on this basis, the outage probability of multiple unmanned aerial vehicles (UAVs) assisted communication is derived under independent Rayleigh fading channels. The simulation results indicate the availability of improving the performance of communication relays and communication networks and further suggest that adaptive modulation can significantly improve system performance.
