| 摘 要： | 讨论了无源超高频射频识别(UHF RFID)系统的信号传输过程及性能测试方法,以软件定义无线电方式实现了符合ISO/IEC18000-6C标准的无源标签的部分性能测试,研究了部分通信参数动态变化时标签应答功率的变化,并对不同标签的灵敏度进行了测试.所有实验在常规条件下完成,测试研究表明在基带编码采用较小的Tari值、PW为50％以及较高的调制系数时,阅读器能够接收到标签反射回来的最大功率,系统的识别距离最远.

| Abstract: | The signal transmission and measurement method of the passive UHF radio-frequency identification(RFID) system are discussed in this paper. Part of tags communication performance which conforms with the ISO/IEC 18000-6 Type C was obtained by using the software-defined radio test platform. The received power by the platform changes with the communication parameters. Sensitivity of different tags was tested. All experiments were conducted under normal conditions.The measurement results show that the small Tari, half duty cycle (PW) and higher modulation index in baseband signal encoding allow the RFID system to receive larger power, also the RFID system to have larger read range. |
