摘要
介绍了目前RFID系统的发展趋势,分析了ISO/IEC18000-4协议中被动反向散射式RFID系统的工作原理和技术规范,提出了一种遵循该协议的2.45GRFID阅读器的设计方案,支持飞利浦的UCODEHSL标签。文章重点介绍了编码解码技术、调制解调方式、防碰撞算法和零中频技术等。
After the trend of the developing of RFID system being introduced, the principle of the passive backscatter RFID system, which is prescribed in ISO/IEC18000-4, are analysised. A scheme to realize the 2.45G RFID system under this protocol and supporting philips＇s UCODE HSL is proposed in this paper. The encoding, decoding, modulation, demodulation, anticollision and zero- IF technology are also given in detail.
