文中详细说明了该赛事的信道数据收集全过程,另外为该赛事出示了一个根据DL的CSI反馈参照构架:QuanCsiNet,完成了真正信道场景收集的高维空间信道数据信息的缩小、量化分析、反馈和复建,为AI在未来通信系统中的具体布署和应用确立了基本。真正信道场景为图1所显示的公司办公室场景,调频发射机在图上所显示部位固定不动,接收器沿小红点运动轨迹健身运动。

对精确测量获得的真正信道数据信息开展图2所显示的预备处理,获得最后应用的数据。图1评测信道数据信息场景平面图图2评测信道数据处理方法步骤QuanCsiNet的网络架构如下图所显示。伺服电机用以对CSI开展svm算法和缩小,量化分析控制模块用以将缩小精确测量值用比较有限位表明,转换为比特流有助于具体系统软件储存和传送;逆量化分析控制模块用以将比特流修复成缩小精确测量值,译码器用以特点压缩包解压和信道修复。

图3QuanCsiNet网络架构从总体上,文章内容初次对于评测信道数据信息开展解决,明确提出了一种真正信道场景下的CSI反馈构架,为事后科学研究出示了可拓展的参照设计方案。导入了量化分析和逆量化分析控制模块,将反馈精确测量值转换为比特流,切合实际系统软件储存传送规定。评定了根据DL的CSI反馈计划方案在具体信道自然环境中的性能,促进事后科学研究和具体布署。

整体而言,文中对真正信道场景下收集的信道数据信息开展解决,设计方案了一种以比特流方式开展反馈的根据DL的CSI反馈构架,并考量了其复建性能与复杂性,以求大量学者为智能通信的具体运用做出贡献。毕业论文下载地址:(请戳这里)引用格式:JiajiaGuo,XiangyiLi,MuhanChen,PeiwenJiang,TingtingYang,WeimingDuan,HaowenWang,ShiJin,QuanYu,“AIEnabledWirelessCommunicationswithRealChannelMeasurements:ChannelFeedback”,JournalofCommunicationsandInformationNetworks,vol.5,no.3,pp.310-317,Sep.2020.文中由毕业论文创作者供稿。热烈欢迎研究组递送成效宣传稿(可在文章内容正下方留言板留言在线留言)!作者简介JiajiaGuo(郭欢欢)receivedtheB.S.degreefromNanjingUniversityofScienceandTechnology,Nanjing,China,in2016,andtheM.S.degreefromUniversityofScienceandTechnologyofChina,Hefei,China,in2019.HeiscurrentlyworkingtowardsthePh.D.degreeininformationandcommunicationsengineering,SoutheastUniversity,China.Hisresearchinterestscurrentlyinclude,deeplearning,neuralnetworkcompression,massiveMIMO,andmachinelearningincommunications.XiangyiLi(李湘宜)receivedtheB.S.degreefromSchoolofMathematics,TianjinUniversity,Tianjin,China,in2017,andtheM.S.degreefromCentreforAppliedMathematics,TianjinUniversity,in2020.SheiscurrentlyworkingtowardthePh.D.degreeininformationandcommunicationsengineering,SoutheastUniversity,China.HermainresearchfocusesondeeplearningapplicationinwirelesscommunicationandmassiveMIMOsystems.MuhanChen(陈慕涵)receivedtheB.S.degreefromtheSchoolofInformationScienceandEngineering,SoutheastUniversity,Nanjing,China,in2019.SheiscurrentlyworkingtowardtheM.S.degreewiththeSchoolofInformationScienceandEngineering,SoutheastUniversity,Nanjing,China.Herresearchinterestscenterarounddeeplearningapplicationsinwirelesscommunicationsystems.PeiwenJiang(姜培文)receivedtheB.S.degreefromSoutheastUniversity,Nanjing,Chinain2019.HeiscurrentlyworkingtowardthePh.D.degreewiththeSchoolofInformationScienceandEngineering,SoutheastUniversity.Hisresearchinterestsincludedeeplearning-basedchannelestimationandsignaldetectionincommunications.TingtingYang(杨婷婷)receivedherB.Sc.andPh.D.degreesfromDalianMaritimeUniversity,China,in2004and2010,respectively.SheiscurrentlyaResearchProfessoratPengChengLaboratory,China.Herresearchinterestsareintheareasofmaritimewidebandcommunicationnetworks,AI-empoweredwirelesscommunications.SheservesastheAssociateEditor-in-ChiefoftheIETCommunications,aswellastheAdvisoryEditorforSpringerPlus.WeimingDuan(段为明)isnowaSeniorEngineerinPengChengLaboratory.HereceivedhisM.S.degreeincommunicationandinformationsystemfromtheUniversityofElectronicScienceandTechnologyofChinain1999.Inthesameyear,hejoinedHuaweiWirelessResearchDepartmentinShanghaiandhasworkedtherefor20years.Hehasworkedonbasebandalgorithmfor3G/4g,advancedreceiverfor4g,waveformconceptresearchfor5G,andhasalsobeendeeplyinvolvedinlow-levelalgorithmlibraryoptimizationtospeeduplargescalesystemsimulation.HaowenWang(王浩文)isaSeniorEngineerofLaboratoryofBroadbandWirelessTechnology,ShanghaiInstituteofMicrosystemandInformationTechnology,ChineseAcademyofSciences.HereceivedhisB.S.andM.S.degreesfromEEdepartmentandCollegeofSoftwareofFudanUniversity.InSIMIT,HaowenisaleaderofwirelesstechnologyRDgroup.Hehasmanyyearsofexperienceinthetestandverificationforthenewtechnologiesofwirelesscommunications.HisjobandresearchinterestsincludeRFdataacquisition,channelmeasurement,verificationandtestsolution.ShiJin(金鼎)[correspondingauthor]receivedhisB.S.degreeincommunicationsengineeringfromGuilinUniversityofElectronicTechnology,Guilin,China,in1996,hisM.S.degreefromNanjingUniversityofPostsandTelecommunications,Nanjing,China,in2003,andhisPh.D.degreeininformationandcommunicationsengineeringfromSoutheastUniversity,Nanjing,in2007.FromJune2007toOctober2009,hewasaResearchFellowwiththeAdastralParkResearchCampus,UniversityCollegeLondon,London,U.K.HeiscurrentlywiththeFacultyoftheNationalMobileCommunicationsResearchLaboratory,SoutheastUniversity.Hisresearchinterestsincludespacetimewirelesscommunications,randommatrixtheory,andinformationtheory.HeservesasanAssociateEditorfortheIEEETransactionsonWirelessCommunications,IEEECommunicationsLetters,andIETCommunicatio ns.Heandhiscoauthorshavebeenawardedthe2011IEEECommunicationsSocietyStephenO.RicePrizePaperAwardinthefieldofcommunicationtheoryandthe2010YoungAuthorBestPaperAwardbyIEEESignalProcessingSociety.QuanYu(于全)receivedhisB.S.degreeinradiophysicsfromNanjingUniversity,China,in1986,hisM.S.degreeinradiowavepropagationfromXidianUniversity,China,in1988,andhisPh.D.degreeinfiberopticsfromtheUniversityofLimoges,France,in1992.HeiscurrentlyaResearchProfessoratPengChengLaboratory.Hismainareasofresearchinterestarethearchitectureofwirelessnetworksandcognitiveradio.HeisanAcademicianoftheChineseAcademyofEngineeringandthefoundingEditor-in-ChiefoftheJournalofCommunicationsandInformationNetworks.版权文章内容,没经受权严禁转截。
