【摘要】 基于超高频RFID的实时定位系统将大大拓展RFID的应用。在研究超高频RFID数据传输原理的基础上,提出了基于超高频RFID的实时定位系统的基本架构,并在Matlab/Simulink中进行了整个系统的行为级建模。此外,还对RFID收发机和信道的非理想因素进行了详细的建模来模拟实际的工作环境。仿真结果验证了模型的可靠性,并为后面的实现提供了指导。更多还原

【Abstract】 Real time locating system(RTLS) based on ultra-high frequency(UHF) Radio Frequency Identification(RFID) will greatly impel the application of RFID.The architecture of RFID-based RTLS was proposed and the whole system was modeled in Matlab/Simulink based on the research on the principle of UHF RFID data transmission.In addition,non-ideal factors of RFID transceiver and propagation channel were strictly modeled to simulate real operating condition.Simulation results verify the reliability of the model and direct the implementation.更多还原
