摘要

在无线射频识别（RFID）系统中，物理层上恢复冲突标签可有效提高系统识别效率.然而在超高频（UHF） RFID系统中，频率漂移是一普遍现象，它对物理层的冲突标签恢复有一定的影响.本文针对频率漂移的标签冲突恢复问题，采用径向基函数（RBF）网络分离算法对冲突信号分离，并利用FM0电平边沿跳变的原理实现解码，以此实现冲突标签信号恢复.实验结果表明，当发生频率漂移时，本文的方法在误码率和分离效率上均优于传统算法.

Abstract

In RFID systems

the recovery of collision tag signals on a physical layer could enhance identification efficiency.However

frequency drift is very common for ultra-high frequency (UHF) RFID systems and will have an influence on the recovery on the physical layer.For the problem of the recovery with the frequency drift

this paper adopts a Radius Basis Function (RBF) network to separate the collision signals

and decode the signals based on FM0 code to recovery the collided RFID tags.The numerical results show that

the method in this paper has better performance on bit error rate (BER) and separation efficiency than conventional methods when the frequency drift occurs.
