Recovery of Collided RFID Tags With Frequency Drift on Physical Layer
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.
