摘要
论述了基于DSP技术的声表面波射频识别(SAW RFID)阅读器的设计方法。在此基础上给出了阅读器的硬件设计和与多个标签识别的流程图。最后对标签的反碰撞问题进行了研究。
The design method of the SAW RFID reader based on DSP technology is introduced.On the basis of the description of SAW RFID system,the reader's hardware design and flow chart of several tags identification are given. Finally, the tag anti-collision problem is studied.
