Abstract: In order to recognize multi-label,researchers have proposed several anti-collision algorithms.In this paper,an algorithm based on CDMA reservation ALOHA approach is presented for solving the RFID anti-collision problems.The algorithm’s identification process is also analyzed.Markov chain is introduced to model the CDMA Reservation-ALOHA.The label throughput based on the algorithm is analyzed.Finally the experimental results are given.

摘要: 为了实现多标签的读取,对射频识别(RFID)系统的防碰撞算法进行了研究,提出了一种基于码分多址的预约ALOHA的防碰撞算法,在分析该算法的识别过程后,引进马尔可夫链建模,并根据此模型对算法的性能进行了分析。通过仿真实验验证了算法的可行性。
