基于圆形可重构智能超表面阵列的单基站定位方法
Single Base Station Positioning Using Circular Reconfigurable Intelligent Surface Array
摘要
Abstract
Wireless localization technology is crucial in the era of the Internet of Things(IoT).In outdoor open scenarios,GPS can provide meter-level precision positioning.However,in some special application scenarios,such as indoor case,the accurate location information relies on additional deployed base stations.Typically,the location information of a device requires at least three positioning base stations to operate simultaneously,which is provided through geometric calculation.In recent years,with the development of reconfigurable intelligent surfaces(RIS),their flexibility has provided new ideas for high-precision positioning based on single base station.The single base station positioning technology based on RIS provides the location information of the positioning terminal by simultaneously estimating the target azimuth and target distance.This system has the characteristics of low complexity,high accuracy,and low cost,making it promising for indoor positioning,autonomous driving,industrial Internet connectivity,and other fields.关键词
