RFID系统误码率分析与仿真

Simulation and analysis of code error rate of RFID system

对RFID系统数据通信中不同编码方式与误码率的关系及其信道适应性进行仿真分析.利用Simulink构建了组成RFID系统数据通信所需的调制解调、编码校验等模块,并将这些模块搭建成仿真模型进行仿真分析.结果表明,为了保证RFID系统数据通信的可靠性,需要选择合适的编码方式,采用不超过32位的CRC校验,并使系统通信信道在30 dB以上.选择不同的编码和校验方式将会对RFID系统数据通信误码率产生影响.利用仿真方式对RFID系统进行研究是一种很有价值的研究方式.

Aimed at the simulation analysis of the relation between coding way and code error rate and adaptability of channel,this paper Designed and packed the code/dcode model、CRC model、ook/dook model and established simulation system.The result show that for the credibility of RFID data communication,we choose pefect coding means,use CRC checkout shorter than 32 and make system worked at the channel bigger than 30 db.Different coding and checkout method will have different effort on RFID communication error rate,The analysis has some reference value in the practical application and develop of RFID.
