1/25四川师范大学成都学院本科毕业设计TD-LTE网络优化方案设计学生姓名王明学号2012101063所在学院通信工程学院专业名称通信工程班级2012级广播电视方向指导教师倪磊四川师范大学成都学院二○一六年五月I/25TD-LTE网络优化方案设计学生：王明指导教师：倪磊内容摘要：TD-LTE无线网络优化有两个运行阶段：一是工程优化阶段，第二,运营阶段。本文的研究方向是工程优化阶段。工程优化阶段分为阶段的单站优化,优化集群,整个网络优化阶段。每个阶段的任务是不一样的,但我们的目标是一样的,两个阶段的目标都是相同的，两个阶段的目标是让用户得到最大价值,实现最佳组合的网络覆盖、容量和价值。用户通过无线网络优化方法提高产量和节约成本。为了达到要求的KPI指标，我们针对优化工作：覆盖优化，切换优化，干扰优化，RR优化做出分析。经过这些反复的优化流程以确保广大用户能正常使用LTE无线网路。本文将重点介绍上述工程优化三个阶段的优化流程和方法，以及介绍无线网络优化主要优化任务，还有优化过程中经常遇到的问题和解决方法。关键词：TD-LTE覆盖优化切换优化干扰优化RP优化II/25DesignOfOptimizationinTheTD-LTENetworkAbstract:TheTD-LTEwirelessnetworkoptimization,therearetwooperationstages:oneistheengineeringoptimizationphase,thesecond,theoperationalphase.Inthispaper,theresearchdirectionisengineeringoptimizationPhase.Engineeringoptimizationphaseisdividedintophasessinglestationoptimization,optimizationofthecluster,theentirenetworkoptimizationphase.Eachstagetaskisdifferent,butourgoalisthesame,twoGoalsarethesame,thetwostagesthegoalistoletusersgetthemostvalue,toachievethebestcombinationofnetworkcoverage,capacityandvalue.UsersviawirelessnetworkoptimizationmethodtoIncreaseproductionandsavecost.InordertosatisfythetherequirementsofKPI,weoptimizedwork:coverageoptimization,theswitchoptimization,optimization,RRoptimizationanalysis.AftertheserepeatedoptimizationprocesstoensurethatuserscanusenormallyLTEwirelessnetworks.ThisarticlefocusesThreestagesofoptimizationinengineeringoptimizationprocessesandmethods,andintroducethewirelessnetworkoptimizationmainlyoptimizationtasks,thereareoftenencounteredintheprocessofoptimizationproblemsandsolutions.Keywords:TheTD-LTECoverageoptimizationSwitchtooptimizeInterferenceoptimizationTheRPoptimization.III/25目录前言................................................................................................................................................................11无线网络优化..........................................................................................................................................21.1通信技术简介...............................................................................................................................21.2网络优化的意义...........................................................................................................................22TD-LTE基本原理.....................................................................................................................................42.12G、3G关键技术.........................................................................................................................42.1.1Rake接收技术...................................................................................................................42.1.2信道编码技术.....................................................................................................................42.1.3功率控制技术.......................................................................................................................52.1.4多用户检测技术.................................................................................................................52.1.5智能天线.............................................................................................................................52.2核心技术.......................................................................................................................................62.2.1OFDM技术........................................................................................................................62.2.2OFDM的优点....................................................................................................................72.2.3基于DFT的OFDM有快速算法......................................................................................82.3MIMO技术...................................................................................................................................93TD-LTE网络优化架构............................................................................................................................104网优方案设计.........................................................................................................................................114.1LTE网络优化关键步骤..............................................................................................................124.2网络优化内容..............................................................................................................................134.2.1天馈接反...........................................................................................................................144.2.2弱覆盖优化.......................................................................................................................144.2.3越区覆盖优化.................................................................................................................154.2.4上下行不平衡.................................................................................................................164.2.5无主导小区........................................................................................................
