Research And Design Of TD-SCDMA Repeater

TD-SCDMA mobile communication network will go into commercial period.The repeater,which various equipment providers are researching urging,regarded as the important components in TD-SCDMA system.During the initial time of TD-SCDMA mobile communication network building,there especially need a lot of repeaters which meet coverage requirement to optimize the whole TD-SCDMA network performance. Hence TD-SCDMA repeater research have the important meaning and engineering practical value.The thesis summarizes the development situation and researching actuality of TD-SCDMA mobile communication network and TD-SCDMA repeater,it analyzes the impact of TD-SCDMA repeater to TD-SCDMA mobile communication network,and focus on the impact of TD-SCDMA repeater to TD-SCDMA network performance and network coverage,at the same time,it provide several problems of repeater used on network,according to repeater application principle and TD-SCDMA system characteristic.It researches several methods how to realize the synchronization between repeater and Node B.It designs and simulates TD-SCDMA repeater realization scheme. And the thesis point out engineering application guidelines on repeater radiation,EMC and anti-lightning and so on.The repeater make the network building more flexible and more economic, TD-SCDMA repeater will play the important role on TD-SCDMA network coverage building.The TD-SCDMA repeater development trend is go on deceasing cost and upgrading the suitable capability on bad work environment.At the same time,we also need consider some new characteristic of repeater,and abundant research and validate the repeater's network adaptation.The next step of research is analyzing the interference problems on TD-SCDMA repeater engineering,and researching the repeater radio coverage cause the impact for PHS/WCDMA system and how to resolve the interfere problems among the different radio system.
