| 摘 要： | 无线通信的复杂性影响了RFID系统识别的可靠性,进而阻碍了RFID系统的大规模应用。为全面、客观评价RFID系统可靠性性能,在已知影响RFID系统可靠性的两个主要因素,即RFID读取距离和标签碰撞问题的基础上,研究了ASK通信系统的仿真与误码分析。通过建立仿真模型,绘制出信噪比与误码率的关系曲线,由自由空间传播理论绘制出距离与误码率的关系曲线,最终由误码率与识别率的影射关系,绘制出距离与识别率的关系,从而推出了距离对RFID系统可靠性影响的数学模型。仿真结果表明所得出的数学模型是合适的,可行的。

| Abstract: | The complexity of wireless communication has effect on the reliability of RFID system identification,and then,which prevents the large-scale application of RFID system.To evaluate of RFID system comprehensively and objectively,the simulation and analysis of Bit Error Rate of ASK communication system are given,which are based on the two key factors affecting RFID system,including distance and tags collision.Through establishing simulation model,the relation curves between SNR and Bit Error Rate is given,besides the relation curves between distance and Bit Error Rate is proposed,which is based on the Friis free space equation.Finally,the relation curves and mathematical model between distance and identification probability are presented,which is based on the allude relationship between Bit Error Rate and identification probability.Simulation results show the model is feasible,convenient. |
