Abstract

The autonomous aerial vehicle (AAV)-assisted ambient backscatter communication (AmBC) network has a wide range of applications and can efficiently establish wireless links for Internet of Things (IoT) nodes. In this paper, we analyze the performance of the AAV-assisted AmBC network over Nakagami-

$m$

fading channels. In this network, there are two different transmission links: a legacy link and multiple AmBC links, where one of the AmBC links is randomly selected for backscattering communication. For the randomly selected AmBC link, two main factors caused information outages are analyzed: the energy outage and the interference outage. Based on the probability density function of the Nakagami-m fading channel gain, the closed-form expressions of the outage probabilities are derived by using the Gauss-Laguerre approximation. Furthermore, we calculate the asymptotic outage probability, ergodic capacity, and diversity gain through theoretical derivation. For the air-to-ground legacy link, the reasons of the primary user's outage are analyzed as the transmission outage caused by air-ground channel attenuation and the interference outage caused by the high transmission power of the AmBC link. Building upon different cases, the closed-form expressions of the outage probabilities are also calculated. In addition, the related performance of the legacy link is also further studied. The simulation results show the performance of the two mentioned links under different parameters and verify the effectiveness of the network.

无人机辅助AmBC网络：Nakagami-$m$衰落信道的性能分析

自主飞行器（AAV）辅助环境反向散射通信（AmBC）网络具有广泛的应用范围，可以有效地为物联网（IoT）节点建立无线链路。在本文中，我们分析了aav辅助的AmBC网络在Nakagami-$m$衰落信道中的性能。在该网络中，有两条不同的传输链路：一条遗留链路和多条AmBC链路，其中随机选择一条AmBC链路进行后向散射通信。针对随机选取的AmBC链路，分析了造成信息中断的两个主要因素：能量中断和干扰中断。基于Nakagami-m衰落信道增益的概率密度函数，利用Gauss-Laguerre近似导出了中断概率的封闭表达式。进一步，通过理论推导计算了渐近中断概率、遍历容量和分集增益。针对空对地遗留链路，分析了主用户中断的原因，包括空对地信道衰减导致的传输中断和AmBC链路高发射功率导致的干扰中断。根据不同的情况，计算了停电概率的封闭表达式。此外，还对遗留链路的相关性能进行了进一步的研究。仿真结果显示了两个链路在不同参数下的性能，验证了网络的有效性。

期刊介绍： The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
