论文摘要
在这封信中，我们调查了一个具有无人机的通信系统，在该系统中，在存在多个干扰器的情况下，部署了无人机以与地面节点（GN）进行通信。我们的目标是通过优化其轨迹，但要受到UAV的移动性约束，从而最大程度地提高了无人机的能源效率（EE）。但是，由于目标函数的非凸和分数形式，因此很难解决该法式问题。因此，我们提出了一种基于连续的凸近似（SCA）技术和Dinkelbach的算法来解决它的迭代算法。数值结果表明，所提出的算法可以通过优化的轨迹在吞吐量和能量消耗之间取得更好的平衡，因此与基准算法相比，EE显着改善了EE。
In this letter, we investigate a UAV-enabled communication system, where a UAV is deployed to communicate with the ground node (GN) in the presence of multiple jammers. We aim to maximize the energy efficiency (EE) of the UAV by optimizing its trajectory, subject to the UAV's mobility constraints. However, the formulated problem is difficult to solve due to the non-convex and fractional form of the objective function. Thus, we propose an iterative algorithm based on successive convex approximation (SCA) technique and Dinkelbach's algorithm to solve it. Numerical results show that the proposed algorithm can strike a better balance between the throughput and energy consumption by the optimized trajectory and thus improve the EE significantly as compared to the benchmark algorithms.
