Abstract:Considering that UAVs, serving as base stations, can enhance the flexibility of communication system transmission, reduce transmission delays, and provide temporary communication, this paper proposes a NOMA-assisted UAV downlink communication network model in a Rice fading channel, which is more suitable for air-to-ground transmission. The joint optimization of UAV three-dimensional trajectory, pitch angle, and user clustering is studied to improve the sum rate of the communication system. Among these, cluster… Show more
