Abstract :
In this paper, a multi-tag anti-collision method with collision signal recovery for UHF RFID systems is proposed. Signal recovery of 2 tags or 3 tags is adopted in the algorithm and the frame size is optimized accordingly. Simulation results show that the average system efficiency of the proposed anti-collision algorithm can be up to 67%, while the system efficiency of the algorithms without adopting collision recovery is no more than 36.8%. The influence of non-ideal parameters in different scenarios, such as signal-noise-ratio (SNR) and frequency of clustering, is discussed as well.
