Abstract
This paper presents a novel collided tag signals’s periodic characteristic based radio frequency identification(RFID) tag collision detection method for the ultra high frequency (UHF) RFID. The proposed method utilizes thatperiodicity of tag signals is maintained even under tag collision. In the proposed method, the correlation betweenreceived signal and reference edge signal is used. Simulation result shows that the detection performance usingthe proposed method is about 10 dB better than that of existing method. In addition, the detection performanceswith different magnitude difference, phase difference, delay, number of tags are analyzed.
