“智慧城市”和“中国智造2025”等国家战略提出要重视和促进国家重点社会经济领域物联网的应用，而RFID是物联网的一项非常重要的支撑技术。本项目将光载无线技术引入UHF RFID领域，在分布式天线架构下，针对UHF RFID对光载无线系统提出的新要求和新挑战，围绕集中管控、光纤链路和天线单元三个环节上的具体技术挑战，在模型、机理、机制和方法等层面研究并突破分布式天线协同、高效数模混合信号光纤传输和自干扰消除三项关键技术，解决系统功耗与读取性能之间的矛盾和光载无线链路非线性行为模型两类科学问题，最终为构建面向智能制造的新型光载UHF RFID系统提供理论基础和技术支撑。本项目涉及之前研究相对独立的UHF RFID及光载无线通信两个技术领域，属于交叉融合技术研究；研究内容涉及基于分布式天线架构的光载UHF RFID系统的各个环节，关键技术之间关联性和兼容性较强。

The national strategies“Smart City” and “China Manufacturing 2025” stressed the contributions of “Internet of Things (IOT)” in key social and economic areas. RFID is one of the key enabling technologies for IOT. In this project, radio-over-fiber technique is introduced in UHF RFID systems to enable a distributed antenna architecture. In order to address the new technical requirements and chanlleges in new UHF RFID-over-fiber systems, we will be working on three key techniques including distributed antenna cooporation, efficient analog&digital hybrid fiber transmission and self-interference mitigation. Two kinds of basic scientific problems are expected to be investigated: the tradeoff between the system power and reading performance, and behavorial modeling of nonlinearity in radio-over-fiber links. The outcomes of this project is expected to provide theoretical and technical reference to building up UHF RFID-over-fiber system for future Smart Manufacturing application. This project combines two research topics: UHF RFID and RoF, thereby conducting study in a cross area . This project involves most concerns of UHF RFID-over-fiber systems, and the techniques has strong relevance between each other.
