| 摘 要： | 针对无线射频识别技术中的读写碰撞问题提出了一种新的标签防碰撞算法。该算法利用陪集分解理论将电子标签分组，限定每组标签在规定的时隙响应。根据查询码和碰撞特征位，阅读器可在一个时隙内识别出一组标签。Matlab仿真结果表明，在多标签时该算法的时隙利用率和吞吐率优于二进制搜索算法和动态帧时隙算法。

| Abstract: | A new tags anti-collision algorithm was proposed for the reader collision problems in the Radio Frequency IDentification (RFID) technology. It divided tags into groups based on the coset partition theory, and restricted each group to response in a fixed timeslot. According to the query codes and collision flag bits, the reader could identify a group of tags in one slot. The Matlab simulation results show that, compared with the binary search algorithm and dynamic frame timeslot algorithm, the proposed algorithm improves the slot utilization and throughput when the number of tags is large. |
