摘要

本研究在matlab /SimulinkR中开发了一种用于无源超高频RFID的单输入多输出模拟器。标签定位是通过相位差到达技术实现的。在发动机测试环境中进行了通道测量活动。在几个视线和非视线标签位置测量散射参数。利用测量到的S参数在模拟器中模拟真实的室内多径信道。该模拟器估计了测量活动中几个标签位置的准确到达方向。几何计算角度与模拟角度的最大误差为32°，最小误差为0.4°。

Measurement based indoor SIMO RFID simulator for tag positioning

In this research, a single-input multiple-output simulator for passive UHF RFID is developed in MatlabR/SimulinkR. Tag localization is achieved via a phase difference of arrival technique. A channel measurement campaign was conducted in an engine test environment. Scattering parameters were measured at several line-of-sight and non-line-of-sight tag positions. The measured S parameters were used in the simulator to emulate a real indoor multipath channel. The simulator estimates accurate direction of arrival at several tag positions of the measurement campaign. There is a maximum error of 32° and minimum of 0.4° between the geometrically calculated and simulated angles.
