某办公大楼4G通信分布系统的优化摘要本文对4G与分布系统的关键技术进行了介绍,对4G分布系统在设计、建设、优化过程中需要着重考虑的因素如4G分布系统干扰隔离、单双通道天馈系统选型与合路方式进行了探讨。在此基础上为某办公大楼设计了一种双通道4G分布系统改造方案,并付诸实施,并针对实施后存在的影响速率提升的问题进行了专题优化。最后对系统进行了验收性测试,达到了设计的要求。本论文主要研究内容如下:首先,介绍了论文研究的背景,引出了实施该研究的重要性,其次,介绍了论文中所用到的4G网络以及分布系统的关键技术,并对4G分布系统在多系统设计中的干扰隔离进行了专门分析,这就为下文的开展做好了铺垫。再次,是对通信分布系统的优化设计,根据要求,在对某办公大楼进行全面摸底的情况下,设计了一种双通道4G分布系统改造方案以及施工方面需要注意的问题。最后,针对分布系统建设完成后部分区域存在的低速率问题,如单双通道的选择、MIMO天线功率输出差值、室外宏站对分布系统的干扰影响进行了重点分析,同时对参数导致低速率的一种情况进行了介绍,提出了自己的一些见解,希望能对此类系统的优化提供一些可以参考的建议。关键词:分布式系统,多模覆盖,双通道模式,参数优化,干扰优化AbstractThispaperfocusesonthekeytechnologiesof4Ganddistributedsystemareintroduced,thefactorsof4Gdistributionsystemintheoptimizationdesign,constructionprocess,highlightedtheneedtoconsiderifthedistributionsystemof4Ginterferenceisolation,singleanddoublechannelantennasystemselectionandcombinationmethodsarediscussed.Onthisbasis,adualchannel4Gdistributionsystemtransformationschemeisdesignedforanofficebuilding,andputintopractice.Finally,thesystemistested,andthedesignrequirementsaremet.Themaincontentsofthisdissertationareasfollows:firstly,introducestheresearchbackground,discussestheimportanceoftheimplementationoftheresearch,thenintroducesthekeytechnologiesof4Gnetworkusedinthepaperandthedistributionsystem,andthesystemdesigninthedistributionsystemof4Ginterferenceinisolationforaspecialanalysis,itisbelowthelaunchready.Again,istooptimizethedesign,communicationdistributionsystemaccordingtotherequirementsinacomprehensivediagnosticofacaseofofficebuildingdesignofadualchannel4Gdistributionsystemreconstructionschemeandconstructionaspectsneedtopayattentiontotheproblem.Finally,aimingattheproblemsoflowrateareaaftertheconstructionofcompletedistributionsystem,suchassingleanddoublechannelselection,MIMOantennaoutputpowerdifference,outdoormacrostationinterferenceeffectondistributionsystemwasanalyzed,andtheparametersleadtoasituationoflowrateintheintroduction,theauthorputforwardhisownopinionshope,optimizationofthiskindofsystemcanprovidesomereferencesuggestions.Keywords:Distributedsystem,multimodecoverage,dualchannelmode,parameteroptimization,interferenceoptimization目录某办公大楼4G通信分布系统的优化...........................................................................I摘要................................................................................................................................IAbstract........................................................................................................................II第1章绪论....................................................................................................................11.1研究背景和意义.............................................................................................11.2国内外发展现状及趋势.................................................................................11.3研究的主要内容...........
