“…The basic principle of the UAV relay communication adaptive modulation system is that the transmitter at the node selects the optimal modulation method based on the feedback information of the current channel environment, the system block diagram is shown in Figure 1 11 . After receiving the signal, the receiving node estimates the channel condition based on the signal, and feeds back the channel estimation information to the transmitting node 1,12…”

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.
