[RFID] A-Simulator-UHF-RFID-Protocol

Description: Radio Frequency Identification (RFID) systems have recently received a lot of attention in supply chain applications. One of the challenges facing RFID in this application domain is the fast identification of a large number of tags that are simultaneously present in the reader range of an RFID reader. In this thesis, different transmission control strategies were evaluated based on the EPCglobal Class-1 Generation-2 UHF RFID protocol. These strategies focus on incorporating the capture effect and an accurate tag population estimate. To facilitate the evaluation, a Java-based simulator of the MAC layer of the above protocol was implemented.

[VHDL-FPGA-Verilog] UHF-RFID-CRC

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。最后本文提出了一种新颖的UHF RFID系统数字基带电路，区别于一般数字基带电路的地方是：在编解码模块和CRC模块之间加入了卷积编码和维特比译码模块。利用卷积码优良的纠错能力，来解决UHF RFID系统在电磁干扰严重的环境中识别率低、通信速度慢的问题，效果良好。-The first，this paper investigates the f．0rward link and retum link data encodlng method in short range communication types A and B in ISO／IEC 1 8000-6，and deeply analyzes encoding method and technical parameters of Bi—Phase Space(FMO)coding， Pulse IntervaI Encoding(PIE)coding and Manchester coding．We also designed and simulated code circuits and decode circuits of the three encoding method by FPGA experiment platfoml． The second， We discussed the technical principle of error control of the UHF RFID system，especially for the techn0109y of data Verification 肌d calibration，namely cyclic redundancy check that used in IS0／IEC 1 8000·6·The circuits of CRC based on Linear Feedback Shin Register(LSFR)are analyzed行om theonr and realization，and some means of solVing problems are put fon)Irard，then an improved LSFR circuit to implement CRC is designed．For some require fast CRC calculation system，we designed a noVel parallel CRC circuit by using recurslVe fomlula．In the end，we put forw
