摘要

本文提出了一种评估无源超高频射频识别(RFID)标签性能的新方法，该方法基于对其功率谱密度(PSD)的分析，该功率谱密度随时间的变化直接在射频(RF)波段观测。为了在标签响应上重现比特的周期性序列，通过对RFID信号的空中接口的操作，促进了PSD分析。可以绘制出用于清除和反映标签状态的重要推论。报告了该方法在一些市售标签上的应用，并对结果进行了讨论。

RFID air interface setup for power spectral density analysis

This paper presents a new method to evaluate the performance of passive UHF Radio Frequency Identification (RFID) tags based on the analysis of its Power Spectral Density (PSD) calculated over time observations directly in the Radio Frequency band (RF). The PSD analysis is facilitated with the manipulation of the air interface from RFID signals in order to reproduce a periodic sequence of bits on the tag response. Important deductions for scavenging and reflecting states of the tag can be drawn. The application of the method for some commercially available tags is reported and results are discussed.
