摘要

为了解决射频识别系统(RFID)中的多标签防碰撞问题

在分析了时隙AlOHA算法的基础上提出了一种基于混沌序列扩频的时隙ALOHA算法

该算法的标签ID序列通过混沌扩频序列Chebyshev序列扩频而获得扩频信号

阅读器通过接收扩频信号并对其解扩得到标签ID序列.通过建立数学模型对算法进行了分析

仿真实验结果表明扩频ALOHA算法可显著提高系统吞吐量

并且当负载G接近于N时

系统吞吐量Sc接近于最大值.

Abstract

In order to solve the problem of collision between multi-tag in radio frequency identification (RFID) system.This paper proposes RFID anti-collision algorithm based on chaotic sequence slotted ALOHA by analyzing slotted ALOHA algorithm.Address code of labels obtain spread-spectrum signal by chebyshev spread-spectrum code.Reader get address code of labels by receiving spread-spectrum signal.An evaluative model for system efficiency is built

and experimental results show that the algorithm can significantly improve system throughput and when offered load is close to N

the throughput is close to the maximum.
