TD-SCDMA无线网络优化
I.Introduction
Withtherapiddevelopmentofwirelesscommunicationtechnology,TD-SCDMA(TimeDivision-SynchronousCodeDivisionMultipleAccess)wirelessnetworkshavebeenwidelyusedinChina.Asa3G(third-generation)mobilecommunicationtechnology,itscharacteristicsofhighspeed,highcapacity,andstronganti-interferenceabilityhavecausedthepopularityofTD-SCDMAnetworks.
However,duringtheoperationoftheTD-SCDMAnetwork,variousproblemsmayarise,suchasdataloss,callinterruptions,andlowcommunicationquality.Therefore,theoptimizationoftheTD-SCDMAwirelessnetworkiscrucialtoimprovetheperformanceofthenetworkandprovidebetterservicetousers.
ThispaperaimstoanalyzetheproblemsexistinginTD-SCDMAwirelessnetworksandproposeoptimizationstrategiestoimprovenetworkperformance.
