RFID系统性能及识别率优化方法研究

摘要

针对评估射频识别技术RFID(Radio Frequency Identification)系统性能目标区域识别率的影响因素展开研究,从典型无源超高频RFID系统传播模型出发,讨论分析了影响识别率的主要因素,提出了多标签法和干扰抵消法两种识别率的优化方法.并就两种方法分别进行了实验测试,测试结果表明,采用两种方法目标区域识别率能分别提高11％和7.86％,能有效改善无源超高频RFID系统性能.%The target area of the recognition rate evaluation of passive UHF RFID( Radio-Frequency Identification) is an important indicator of the performance of the system,and the research on the factors affecting the recognition rate of the target areais carried out. From the typical passive UHF RFID system communication model, the main factors affecting the recognition rateis discussed. Two recognition rate optimization method,the multi label method and interference cancellation method are proposed. The experimental testing results show that the two methods can improve the recognition rate of the target area of 11％ and 7.86％ respectively,and effectively improve the passive ultrahigh frequency RFID system performance.
