Description: 本文首先研究了IsO／IECl8000．6标准中A、B两类短程通讯的前向链路与返回
链路的数据编码方式，对(FMO)双相间隔编码、(PIE)脉冲间隔编码、曼切斯特码
的编解码方式和技术参数进行了深入的分析，并利用FPGA实验平台对这三种编
码的编、解码电路进行了设计和仿真。然后对UHF RFID系统的差错控制技术原理
进行了探讨，重点研究了ISo／IECl8000．6标准中采用的数据保护与校验技术，即
循环冗余校验(CRC)技术。分析了基于线性反馈移位寄存器(LFSR)实现CRC的电
路，从理论和实现两个方面对其中存在的问题提出了解决办法，设计了一种改进
型线性反馈移位寄存器电路来实现循环冗余校验。对于要求CRC运算速度高的系
统，本文利用了递归的算法设计了一种新型的并行CRC电路。最后本文提出了一
