OnRMap:一种用于大型智能表面的在线无线电映射方法

OnRMap: An Online Radio Mapping Approach for Large Intelligent Surfaces

Herman L. Santos, Victor Croisfelt, Cristian J. Vaca-Rubio, Taufik Abrao, Petar Popovski

AI总结:

OnRMap是一种针对大型智能表面的在线无线电映射方法,无需离线扫描即可定位主动用户与被动元素,实验表明其定位精度高于离线方法,但检测率略有下降。

摘要:

我们介绍了OnRMap,这是一种用于感知和定位发射无线电信号的主动用户以及被主动用户无线电信号照明的环境被动元素的在线无线电映射方法。OnRMap处理大型智能表面接收的信号,并基于信号处理技术生成环境的无线电地图。该方法随后无需离线扫描阶段即可感知和定位不同元素,这对于空间布局频繁变化的环境非常重要。实验结果表明,OnRMap比离线方法具有更高的定位精度,但作为在线方法的代价是检测率有适度下降。

英文摘要:

We introduce OnRMap, an online radio mapping (RMap) approach for the sensing and localization of active users (AUs), devices that are transmitting radio signals, and passive elements (PEs), elements that are in the environment and are illuminated by the AUs' radio signals. OnRMap processes the signals received by a large intelligent surface and produces a radio map (RM) of the environment based on signal processing techniques. The method then senses and locate the different elements without the need for offline scanning phases, which is important for environments with frequently changing spatial layouts. Empirical results demonstrate that OnRMap presents a higher localization accuracy than an offline method, but the price paid for being an online method is a moderate reduction in the detection rate.
