To resolve the collision of RFID tags, this paper studies the influence of clustering on collision tag separation, and introduces the PCA&One_Pro clustering method. The influence of Ricean quasi-static stochastic fading channel on the clustering algorithm is simulated and tested.Firstly, collision tag signals are mapped to an IQ constellation plane, and then a clustering algorithm and a matched filter are performed to separate the collision signal. Finally, the separated signal will be recovered via Miller and FM0, respectively. This work derives and evaluates single-antenna detection schemes for collided radio frequency identification (RFID) signals, i.e. simultaneous transmission of two RFID tags, following FM0. In an ultrahigh frequency (UHF) radio frequency identification (RFID) system, the throughput can be greatly improved by collision resolution on a physical layer when tags collide, and high-performance coding technology can improve the bit error rate (BER) performance of the physical-layer separation. Most of the traditional physical collision .

Abstract. In a passive ultra-high frequency (UHF) radio-frequency identification (RFID) system, tag collision is generally resolved on a medium access control (MAC) layer. However, some of collided tag signals could be recovered on a physical (PHY) layer and, thus, enhance the identification efficiency of the RFID system.We demon-strate this by exploring the differences in amplitudes and phase offsets among signal components, multiple tags can be separated and efficiently decoded using joint decoding. System performance is analyzed with both implementation and simulation.with blind source separation techniques can be used to separate multiple overlapping tag signals. The source signals are modeled as Zero Constant Modulus (ZCM) signals, and the corresponding ZCM algorithms are tested on synthetic and measured data sets.
