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。
Time Division Synchronous Code Division Multiple Access System (TD-SCDMA) uses a number of core technologies to solve the network interference problems, but out of the network system and the complexity of the wireless environment, the emergence of interference is difficult to avoid. TD-SCDMA systems differ from those of Global System for Mobile communications (GSM) and Code Division Multiple Access (CDMA) systems in that TD-SCDMA systems have interference specific to TDD SCDMA systems and that interference in TD-SCDMA wireless networks Factors, we need to understand the characteristics of the network, based on different interference characteristics to consider the existence of different interference, according to the principle of similar to the frequency from the inside to the outside, from hardware failure to network design from different angles to locate the interference and solve.
