Research On The Optimization Of Huanggang CDMA Radio Access Network

CDMA is an advanced mobile communication system that offers high capacity, high quality,integrated service, soft handover, and international roaming. It has the advantages that highanti-interference ability, strong anti multi path fading ability, and high security.With the increase of the user number and service diversity, and the channel conditionchanging caused by building, it is necessary to optimize the CDMA network continuously. Thebad coverage, low voice quality, call drop off, network jamming, low switch off rate are solvedby network optimization, so the network will run in the best state. At the same time, by theoptimization, the network resources are allocated optimally, so the network will run in the bestway to make biggest profit.This thesis focuses on the optimization of Hubei Huang Gang CDMA network. First theactual state of Huang Gang CDMA network is surveyed, then the history of mobilecommunication and the CDMA network, the principles of CDMA2000, the key technologies andoptimization of CDMA2000are discussed in detail. Based on the survey of Huang GangCDMA2000network, the optimization scheme is designed and deployed. After the optimization,the CDMA2000network of Huang Gang is improved.
