摘要: 在射频识别系统应用中, 会经常遇到多移动目标同时进入工作区域的情况.为了防止目标之间的信号干扰, 提出了一种新的算法——随机推迟算法, 并建立了数学模型, 给出了算法的稳定条件.用该数学模型分析了整个射频系统的平均响应时间和吞吐量.计算机仿真结果表明: 该算法的性能达到了系统的要求, 可用于射频识别系统的设计.

关键词: 射频信号, 射频识别, 随机推迟算法

Abstract: The difficulties of recognition when multi-moving targets entered the working area of RFID are often met in applications of thesystem. For avoiding signal interference from each other among all targets an anti-collision algorithm a mathmatical model as well as the stability conditionis proposed. The computer simulation shows that the new algorithm will be of great help in the processof the system design.
