摘要

针对UHF RFID系统识别率受电波多径传播制约的问题，研究了前向与反向相关信道对系统识别性能的影响。将信道分为独立、相关和完全相关3种情形，基于广义莱斯衰落信道模型，推导了识别率的解析计算式。与现有分析相比，此分析给出了任意相关系数和多种信道条件下识别率统一的计算式。仿真实验表明，不同相关系数、信道条件、灵敏度和距离对识别率有影响。

Abstract

The identification rate of UHF RFID system was restricted by multipath propagation effects.The system identification performance was studied considering the correlation coefficient between forward and reverse channels.Based on the generalized Rician fading channel model

the analytical expression of identification rate was derived under independent

full correlation and correlation cases.Compared with the existing analysis

the proposed uniform calculation formula of identification rate was for any correlation coefficient and kinds of channel conditions.The numerical computation and Monte-carlo simulations show that the influences of different correlation coefficients

channel conditions

sensitivity and distance on the identification rate.
