基于虚拟无线电的RFID读写器实现方案

Scheme of realizing RFID reader based on virtual radio

随着通用计算机性能的不断提高,虚拟无线电技术得以发展。根据虚拟无线电处理基带信号具有更好的灵活性、通用性和开放性的优点以及ISO/IEC 18000-6C标准中超高频RFID读写器的特性,在此提出了一种基于虚拟无线电的超高频RFID读写器的实现方案。该方案介绍了常见RFID系统的结构和工作原理,重点阐述了基于虚拟无线电的RFID读写器的整体结构和工作流程,并对接收端算法做了研究与实现。

With the improvement of the general computer performance, the virtual radio technology develops quickly. Ac- cording to the advantages that the virtual radio processing of baseband signal has better flexibility, versatility and openness, and the characteristics of UHF RFID readers in ISO/IEC 18000-6C standard, an impl.ementation scheme of UHF RFID reader based on the virtual radio is proposed in this paper. The the structure and working principle of common RFID systems are in- troduced. The whole structure and workflow of the UHF RFID reader based on the virtual radio are expounded. The algo- rithm for receivering-end was research and realized.
