Abstract

Unmanned aerial vehicle (UAV) has been considered as a widespread technical solution in recent years to meet the explosive data and massive device connections demands. On the other hand, Backscatter communication (BackComm) also equally evolved as a potential candidate to realize future Internet-of-Things (IoT) networks. By deploying BackComm in UAV-enabled IoT system allows an efficient utilization of the network resources, especially, in remote areas and smart cities. In this paper, we investigate the performance of a UAV-assisted multi-node BackComm network over generalized k - μ shadowed fading channel. Closed-form expressions are derived to study the system performance through outage probability and average BER. Additionally, we obtain a simplified asymptotic expression in a high SNR regime, from which we gain insight into how the channel and system parameters affect the overall performance. Finally, simulation results are provided to validate the derived theoretical results.

无人机后向散射无线通信网络性能分析

近年来，无人机(UAV)被认为是一种广泛的技术解决方案，以满足爆炸性数据和大量设备连接的需求。另一方面，反向散射通信(BackComm)也同样发展成为实现未来物联网(IoT)网络的潜在候选。通过在无人机支持的物联网系统中部署BackComm，可以有效利用网络资源，特别是在偏远地区和智慧城市。本文研究了一种无人机辅助多节点BackComm网络在广义k - μ阴影衰落信道上的性能。导出了通过中断概率和平均误码率来研究系统性能的封闭表达式。此外，我们在高信噪比条件下得到了一个简化的渐近表达式，从中我们可以深入了解信道和系统参数如何影响整体性能。最后给出了仿真结果，验证了推导出的理论结果。
