The invention belongs to the technical field of unmanned aerial vehicle communication, and particularly relates to a multi-unmanned aerial vehicle communication rate optimization method. The method comprises the following steps: step 1, establishing a multi-unmanned aerial vehicle communication model; 2, finding out a hovering position by solving a flight-hovering-flight strategy; and step 3, jointly optimizing the trajectory and power of the unmanned aerial vehicle to maximize the channel capacity. Aiming at the problem of calculating the maximum channel capacity by considering factors such as mutual interference and safety distance among the unmanned aerial vehicles when the multiple unmanned aerial vehicles communicate with respective users at the same time and the same frequency, the method comprises the following steps: firstly, converting into a non-convex optimization problem, establishing a multi-unmanned aerial vehicle communication model, and calculating a hovering position by solving a flight-hovering-flight strategy; and finally, solving by using a continuous convex approximation algorithm, and jointly optimizing the trajectory and power of the unmanned aerial vehicle to achieve the maximum channel capacity.

    本发明属于无人机通信技术领域,具体涉及一种多无人机通信速率优化方法。所述方法包括:步骤1:建立多无人机通信的模型;步骤2:通过求解飞‑悬停‑飞策略,找到悬停位置;步骤3:联合优化无人机轨迹和功率,以达到最大化信道容量。本发明针对多无人机在同一时间、同一频率与各自用户通信时,考虑无人机之间相互干扰、安全距离等因素,计算最大信道容量的问题,首先转化为非凸优化问题,建立多无人机通信模型,通过求解飞‑悬停‑飞策略,计算悬停位置,最终利用一个连续的凸近似算法进行求解,联合优化无人机轨迹和功率,达到最大信道容量。
