摘要
简要介绍了近距离无线通信技术及其协议标准EMCA-340使用的防碰撞算法。参考无线射频识别(RFID)有关防碰撞算法原理,总结了多种可在NFC中使用防碰撞算法的改进方案,并对二进制搜索算法和时隙算法的性能进行了比较,最后在此基础之上对更高速率防碰撞算法进行讨论。
The paper introduces near field communication and its anti - collision algorithms in EMCA - 340. It references the application of anti - collision algorithms in RFID, then summarizes several amehorate algo- rithms which can apply to NFC and compares the performance between binary search algorithm and time slot algorithm. Finally, it introduces a new algorithm which is applied to the anti - collision of higher bite rate.
