摘要
本文针对RFID系统中电子标签的射频信号在传输过程中存在的抗干扰能力差的问题,提出了一种滤波算法。该算法利用电子标签在无线传输中的碰撞概率,合理选择读取参数从而提高整体系统的性能。通过分析和仿真,证明了该算法一定程度上提高了电子标签的抗干扰性能,在货物移动速率不高的应用场合中有一定的参考价值。
In this essay,a new filtering method of electronic tag in RFID system has been provided to solve the fact that the capability of the anti-disturbing of RFID tag is relatively poor because of its simple structure. Through analyzing and simulating, we get a conclusion that this method has already improved the appearance.And it will be applied in the situation which does not require realtime reflection.
