1“6G通感算融合”专题!1面向通信感知一体化系统的三维联合定位刘若韵,刘蕊,李佳珉*,潘志文(东南大学移动通信国家重点实验室,江苏南京210096)【摘要】随着通信感知一体化技术的不断发展,移动通信系统将集成雷达传感功能,从而促进智慧城市、智慧交通等新型智能化应用。由于传统雷达单基站的感知精度和感知范围有限,不能发挥大规模网络化移动通信系统的特有优势。因此,提出了一种适用于移动通信系统的多基站协作感知方法。该方法混合波达方向和到达时间差对目标进行3-D联合定位。理论分析结果和仿真结果均表明,该定位算法在小噪声条件下可以达到克拉美罗下界。【关键词】通信感知一体化;波达方向;到达时间差doi:10.3969/j.issn.1006-1010.20240124-0003中图分类号:TN929.5文献标志码:A文章编号:1006-1010(2024)03-0090-05引用格式:刘若韵,刘蕊,李佳珉,等。面向通信感知一体化系统的三维联合定位[].移动通信,2024,48(3):90-94.LIURuoyun,LIURui,LIJiaming,etal.Three-DimensionalJointLocalizationforIntegratedSensingandCommunicationSystems[J.MobileCommunications,2024,48(3):90-94.OSID:扫描二维码与作者交流Three-DimensionalJointLocalizationforIntegratedSensingandCommunicationSystemsLIURuoyun,LIURui,LIJiaming,PANZhiwen(NationalMobileCommunicationsResearchLaboratory,Nanjing210096,China)[Abstract][Keywords]Withthecontinuousevolutionofintegratedsensingandcommunicationtechnology,mobilecommunicationsystemsareintegratingradarsensingtofacilitateemergingsmartapplications,suchassmartcitiesandintelligenttransportation.Giventhelimitedsensingaccuracyandrangeoftraditionalradarwithasinglebasestation,whichdoesnotleveragetheuniqueadvantagesoflarge-scalenetworkedmobilecommunicationsystems,amulti-basestationcooperativesensingmethodsuitableformobilecommunicationsystemsisproposed.Thismethodemploysamixofthedirectionofarrivalandthetimedifferenceofarrivalforthree-dimensionaljointlocalizationoftargets.BoththeoreticalanalysisandsimulationresultsdemonstratethatthislocalizationalgorithmcanachievetheCramer-Raolowerboundunderlownoiseconditions.integratedsensingandcommunication;directionofarrival;timedifferenceofarrival0引言随着时间的推移和技术的进步,移...
