移动环境下RFID系统建模与仿真

Modeling and simulation of RFID system in mobile environment

为了使RFID系统在移动环境中有更好的应用,重点对移动环境下的RFID系统进行了建模与仿真,在移动环境下,采用莱斯衰落信道,实现对RFID系统的收发,并且通过建立仿真模型,绘制出信噪比与误码率的关系曲线。通过接收波形的仿真结果可以看到,标签的回波信息可以被正确的接收。仿真结果证明了该系统的可行性。

In order to make the RFID system has better application in a mobile environment, focuses on the RFID system in the mobile environment modeling and simulation. In the mobile environment, u- sing a Rice fading channel, the transmitter and receiver of RFID system are achieved, and through es- tablishing simulation model, the relation curves between SNR and Bit Error Rate is given . Simulation results of the receiver waveforms show that tag backscatter information is correctly received, which of- fers the reasonable design of RFID system.
