摘要

无人机(UAV)作为中继传输平台受到了国内外研究人员的广泛关注。本文研究了非对称衰落信道下的无人机中继传输系统,提出了输出信噪比最大化准则下的波束形成(BF)优化方案,并推导出系统中断概率、遍历容量和平均误符号率等无线通信系统主要性能指标的理论表达式。通过计算机仿真验证了本文提出的中继传输方案及性能分析的正确性,并定量分析了天线数量、信道参数以及功率分配对系统性能的影响,为无人机中继传输系统的设计及性能评估提供了参考和依据。

Abstract

The application of unmanned aerial vehicles (UAVs) in relay transmission systems has received more and more attention recently. This paper presents a study of a UAV relay transmission system over asymmetric fading channels. Using the maximization of the output signal-to-noise ratio as the design criterion, the optimal beamforming (BF) for the relay system is first obtained. Then, the new accurate expressions for the outage probability, ergodic capacity and average symbol error rate are all derived. Finally, computer simulations demonstrate the validity of the proposed relay transmission scheme and its performance analysis, and provide a quantitative study of the effect of antenna number, channel parameters and power allocation on system performance. Our work can provide some useful reference and foundation work to the system engineer for the purpose of designing a UAV relay transmission system and evaluating its performance.
