摘要:

无人机(UAV)中继通信是实现远距离点对点无线通信的一种重要技术手段。为提高无人机中继通信系统链路传输的可靠性,提出基于空时分组编码的无人机放大转发中继通信传输方案,并基于双跳链路遍历容量最大化的准则给出了无人机最佳航迹规划方法,并进一步利用FM-EM算法给出了基于空时分组编码无人机中继通信系统的中断概率及遍历信道容量计算公式。计算机仿真表明:提出的方法显著优于传统的单发单收(SISO)无人机中继通信系统。

Abstract:

Unmanned Aerial Vehicle (UAV) relay communication is an important technical scheme for long range point-to-point wireless communications. To improve the reliability of transmission link for the UAV relay communication system, a novel UAV relay transmission scheme is proposed based on space-time block coding. According to the criterion of maximizing the average mutual information of the dual-hop link of the UAV relaying communication system, an optimal path planning method for the UAV relay communication system is presented. The outage probability and ergodic capacity of the UAV relay communication system are derived using Finite-Mixture with Expectation-Maximization (FM-EM) algorithm. The computer simulation results indicate that the proposed scheme is superior to the traditional Single-Input Single-Output (SISO) UAV relay communication scheme.
