Abstract

In passive ultra-high frequency (UHF) radio frequency identification (RFID) system, tag collision is generally resolved on a medium access control (MAC) layer. However, the collided signals are in fact recovered on a cross-physical (PHY)-MAC layer to enhance identification efficiency. This paper adopts the cross-layer approach to propose an unsupervised clustering algorithm which could directly separate the collision RFID signal on the PHY layer. The advantage of the proposed algorithm is to have lower computational complexity than traditional unsupervised clustering methods, like k-means. Moreover, the proposed algorithm does not depend on prior known prefix signals as training data. Simulation results show that the proposed approach has better identification efficiency performance than traditional pure MAC-layer approaches regardless of the number of tags
