摘要: 针对无人机(UAV)辅助的卫星通信系统下行链路，该文研究了基于多天线波束成形和协作非正交多址(NOMA)技术相结合的多用户传输系统。首先，在UAV采用多天线和NOMA技术服务多个用户的情况下，基于用户平均信干噪比最大化准则，提出一种利用角度信息的波束成形方案。其次，在卫星-UAV链路服从相关阴影莱斯分布，而UAV-地面用户链路服从Nakagami-m分布的条件下，推导出系统的中断概率闭合表达式。然后，为了进一步分析系统性能，还推导了高信噪比条件下系统的中断概率近似表达式。最后，计算机仿真验证了理论分析的正确性和所提方案的优越性。Abstract: Multi-user transmission system combined multi-antenna beamforming with cooperative Non-Orthogonal Multiple Access (NOMA) technique is investigated for Unmanned Aerial Vehicle (UAV) assisted satellite communication system. Firstly, in case that UAV employs multi-antenna and NOMA technique to serve multiple users, a beamforming scheme is proposed to maximize the average signal-to-interference-plus-noise ratio by using angle information of users. Secondly, under the condition that the satellite - UAV link follows the correlated Shadowed-Rician fading while the UAV - terrestrial link follows Nakagami-m fading, the closed-form expressions of outage probability for system are derived. Furthermore, the asymptotic outage probability formulas in the high signal-to-noise ratio regime are also developed to analyze the system performance. Finally, computer simulations are provided to validate the correctness of the theoretical analysis and the superiority of the proposed scheme.
