| 中文摘要: |
| 超高频RFID系统的无源标签通过调制来自读写器的射频信号获取能量,并将其反向散射,从而将信息传递回读写器.为了使标签从读写器信号中取得更多的能量并降低能量消耗,超高频RFID系统采用了特殊的编码方式.本文介绍了ISO/IEC 18000-6标准中A、B两类短程通信的调制编码方式,系统地分析了FM0双相间隔编码和脉冲间隔编码(PIE)的特点,并用FPGA实现了这两种编码的编解码电路. |

| The passive tag transmits information to the interrogator by modulating the incident energy and reflecting it back to the interrogator in UHF RFID system.In order to make the tag obtain more energy from the radio frequency signal of the interrogator,a special encoding method is designed for the UHF RFID system.This paper introduces the two short-range communication types of A and B in ISO/IEC 18000-6,systematically analyzes the characteristics of FM0 Bi-Phase Space and pulse interval encoding（PIE）,and implements the codec systems of the two types coding based on FPGA. |
