在无源超高频(UHF)射频识别(RFID)系统中,在物理层上回收碰撞标签信号可以提高识别效率。然而,频率漂移在超高频RFID系统中非常普遍,并且会对物理层的恢复产生影响。为了解决频率漂移的恢复问题,本文采用径向基函数(RBF)网络对碰撞信号进行分离,并通过FM0对信号进行解码,恢复碰撞的RFID标签。数值结果表明,在发生频率漂移时,与传统方法相比,该方法具有更好的符号错误率和分离效率。
In a passive ultra-high frequency ( UHF ) radio frequency identification ( RFID ) system, the recovery of collided tag signals on a physical layer can enhance identification efficiency. However, frequency drift is very common in UHF RFID systems, and will have an influence on the recovery on the physical layer. To address the problem of recovery with the frequency drift, this paper adopts a radial basis function ( RBF ) network to separate the collision signals, and decode the signals via FM0 to recovery collided RFID tags. Numerical results show that the method in this paper has better performance of symbol error rate ( SER ) and separation efficiency compared to conventional methods when frequency drift occurs.
