环境反向散射通信技术最近已经被引入，并且由于不需要外部电源或专用载波发射器，因此正迅速成为自维持通信系统的有前途的选择。通过利用现有的RF信号资源，环境反向散射技术可以支持可持续和独立的通信，从而开辟一系列全新的应用，促进物联网（IoT）的发展。在这篇文章中，我们研究了环境后向散射与无线供电通信网络（WPCN）的集成。我们首先提出了一个概述的后向散射通信系统的重点是新兴的环境后向散射技术。然后，我们提出了一种新的混合发射机的设计，结合环境后向散射和无线供电通信的优点。此外，在认知无线电环境中，我们引入了多址方案来协调混合数据传输。性能评估表明，混合发射机优于传统的设计。此外，我们还讨论了与环境后向散射网络相关的开放问题。
Ambient backscatter communication technology has been introduced recently, and is quickly becoming a promising choice for self-sustainable communication systems, as an external power supply or a dedicated carrier emitter is not required. By leveraging existing RF signal resources, ambient backscatter technology can support sustainable and independent communications and consequently open up a whole new set of applications that facilitate Internet of things (IoT). In this article, we study an integration of ambient backscatter with wireless powered communication networks (WPCNs). We first present an overview of backscatter communication systems with an emphasis on the emerging ambient backscatter technology. Then we propose a novel hybrid transmitter design by combining the advantages of both ambient backscatter and wireless powered communications. Furthermore, in the cognitive radio environment, we introduce a multiple access scheme to coordinate hybrid data transmissions. The performance evaluation shows that the hybrid transmitter outperforms traditional designs. In addition, we discuss open issues related to ambient backscatter networking.
