Abstract

In this paper, a 2.5D positioning system is analyzed, based on Received Signal Strength (RSS) measurements, collected from narrowband RF transmissions. The mobile node of the considered system uses multiple closely spaced receivers, collecting RSS measurements and combining them to mitigate multipath effects. Using simulations and optical approximation, the effect of antenna directivity on the positioning accuracy is analyzed. Moreover, a simple iterative method is proposed, that further improves the accuracy obtained using the multipath mitigation technique.

天线方向性对基于多射频收发器的2.5D定位技术的影响
本文分析了一种基于接收信号强度(RSS)测量的2.5D定位系统。所考虑的系统的移动节点使用多个紧密间隔的接收器,收集RSS测量值并将它们组合起来以减轻多径效应。采用仿真和光学近似方法,分析了天线指向性对定位精度的影响。此外,提出了一种简单的迭代方法,进一步提高了使用多径缓解技术获得的精度。
