面向通信感知一体化系统的三维联合定位
Three-Dimensional Joint Localization for Integrated Sensing and Communication Systems
摘要
Abstract
With the continuous evolution of integrated sensing and communication technology,mobile communication systems are integrating radar sensing to facilitate emerging smart applications,such as smart cities and intelligent transportation.Given the limited sensing accuracy and range of traditional radar with a single base station,which does not leverage the unique advantages of large-scale networked mobile communication systems,a multi-base station cooperative sensing method suitable for mobile communication systems is proposed.This method employs a mix of the direction of arrival and the time difference of arrival for three-dimensional joint localization of targets.Both theoretical analysis and simulation results demonstrate that this localization algorithm can achieve the Cramér-Rao lower bound under low noise conditions.关键词
