基于分组码的改进型防碰撞算法研究

摘要

Based on the multi-tree anti-collision algorithm, this paper proposed an improved anti-collision algorithm based on block codes(IABC). It used the block code to encode the tag ID. By mathematical analysis.it accurately predicted the total number of time slots required for the tag identification in IABC algorithm. Simulation results show that the IABC algorithm has faster identification speed and higher efficiency.%在多叉树防碰撞算法的基础上,应用分组码对标签识别码进行编码的方法,提出了一种基于分组码的改进型防碰撞算法(IABC算法).通过数学分析,准确地描述了IABC算法识别标签所需的时隙数.仿真结果表明,IABC算法具有较快的识别速度和较高的识别效率.
