摘　　要：时分同步码分多址系统(TD-SCDMA)采用了多项核心技术来解决网络中的干扰问题,但出于网络系统和无线环境的复杂性,干扰的出现很难避免。TD-SCDMA系统与全球移动通信系统(GSM)和码分多址系统(CDMA)的干扰模型有所差异,有着时分双工(TDD)系统特有的干扰存在方式,分析TD-SCDMA无线网络的干扰因素,需要在了解该网络特点的基础上,根据不同的干扰特征考虑不同的干扰存在方式,依据由内到外、频率相近的原则进行,从硬件故障到网络设计的不同角度进行干扰的定位和解决。TD-SCDMA adopts some core technologies and solves the interference problems in the network.However,due to the complexity of network system and wireless environment,the interference is not avoidable.TD-SCDMA system possesses the specific interference-existing way,which is different from interference patterns of GSM and CDMA system.Analysis on the interference factors of TD-SCDMA wireless network should be based on network characteristics.Different interference-existing ways,should be considered in accordance with the different interferences,including with principle from inside to outside and the similar frequency.And from the different angles of the hardware failure and the network design,the localization and solution of interference is conducted.
