摘要
该文利用强大的数学工具Matlab和仿真工具Simulink对RFID系统的通信框架进行搭建和仿真,其中主要对通信中不同的编解码方式进行仿真。通过对仿真结果的比较和分析,来选择可靠的编码方式。简单的编码只能提供初步的检错和同步信息,为此还要选择合适的校验方式以提高通信的可靠性。采用CRC校验,并使信道信噪比在30dB以上,仿真显示可以进行可靠的数据传输。对RFID系统的计算机仿真是很有意义的一项工作。
Aimed at the simulation analysis of the relation between code mode and bit error ratio of channel in the RFID system, this paper is to design and pack the communication models and establish the simulation system using the simulation tools of Matlab and Simulink. The result shows that we should choose the proper code mode to improve the credibility of RFID system communication. The system can transmit data credibly by using CRC checkout and making the system work at the channel which its SNR is above 30dB. The simulation for RFID system is a very significant job.
