摘要

针对RFID系统的频率干扰和标签干扰，提出了一种可行的TDMA-FDMA解决方案。该方案优先解决标签干扰，这是解决频率干扰的前提。由于时间和频率分配算法运行在中心计算机上而不是读写器上，因此与其他分布式方法相比，该方法可以彻底消除RFID读写器碰撞，保证读写器有更多的通信时间和更高的扫描效率。然后设计了一种基于退火的Hopfield神经网络算法来解决读者的时间分配和频率分配问题。该算法将为可能发生碰撞的阅读器分配不同的时隙，让阅读器与标签进行通信。仿真结果验证了该算法的可靠性和有效性。

Solution to both frequency interference and tag interference of RFID system

A feasible and realizable TDMA-FDMA Solution to Both Frequency Interference and Tag Interference of RFID System was presented. The solution gave priority to solving tag interference, which is the prerequisite of solving frequency interference. Because the time and frequency assignment algorithm run on center computer but readers, the proposed method could eliminate thoroughly RFID reader collision and ensure readers have more communication time and higher scanning efficiency, compared to other distributed method. Then an Anneal based Hopfield Neural Network algorithm was designed to solving time assignment and frequency assignment for readers. By the algorithm, readers that possibly collide will be assigned different time slots in which readers could communicate with tags. Simulation results tested the reliability and efficiency of the proposed algorithm.
