摘要
随着TD-SCDMA系统在我国大规模建设以至逐步商用,TD-SCDMA系统的无线网络规划变得尤其重要。着重分析时分双工+多时隙、智能天线和联合检测等技术对网络规划的影响,并从无线覆盖规划、扰码规划方面讨论TD-SCDMA无线网络规划的特点,接着阐述TD-SCDMA无线网络规划的详细流程,最后结合网络仿真的结果,分析导频强度、导频信噪比、导频污染、最好服务小区、接力切换等问题。
TD- SCDMA system is gradually constructed and enters into commercial use in China, so, radio network planning for this system has become more important. This paper emphatically analyses the influences of the new technologies, such as time division duplex plus multi - slot and smart antenna plus joint detection on the network planning of TD - SCDMA. And the characteristics of network planning are discussed form radio coverage planning and scrambling code planning. Then a detailed process of radio network planning is described. Finally, according to network simulation result, such key issues as the best server coverage, pilot intensity, pilot pollution, demodulation threshold and baton handover coverage are analyzed.
