论文摘要
无人驾驶汽车（UAV）最近引起了学术界和行业的重大兴趣。在无人机的广泛使用中，本文考虑了无人机与可重新配置的天线（RA）在存在褪色和阴影效果的情况下，这是由于城市地区的高建筑物和摩天大楼而引起的。更确切地说，RA提供通过镜像激活模式（MAP）接收信息，以便仅使用一个射频（RF）链，可以在误差概率下实现接收多样性。此外，可以使用降低成本的RA来利用基于媒体的调制（MBM）用于数据传输的数据传输技术。为了量化所提出的无人机系统的性能，我们通过将近似的通道模型与无人机的标准化研究一起考虑了整体误差概率的紧密上限。结果表明，RAS可以使整个系统在错误性能方面对阴影和褪色效应更具弹性，并且可以节能。
Unmanned aerial vehicles (UAVs) have attracted significant interest from the academia and industry most recently. Motivated by the wide usage of UAVs, this paper considers UAV communication with reconfigurable antenna (RA) in the presence of fading and shadowing effects which occur due to tall buildings and skyscrapers in urban areas. More precisely, RA offers to receive information through mirror activation patterns (MAPs) so that it can achieve a receive diversity with decreased error probability by using only one radio frequency (RF) chain. Also, media based modulation (MBM) technique for data transmission with MAPs can be exploited by using RAs with reduced cost. To quantify the performance of the proposed UAV system, we derive a tight upper bound for the overall error probability by considering approximated channel model to the standardization studies for UAVs. The results have shown that RAs can make the overall system more resilient to shadowing and fading effects in terms of error performance, and they are energy efficient.
