TD—SCDMA和WCDMA联合组网的可行性研究

WCDMA和TD-CDMA是第三代移动通信系统的主流标准，在传输速率，组网方式和支持对称／非对称业务等方面有着各自不同的特点，因此将两者有效结合，达到3G网络的最佳性能是一个值得探讨的问题。未来的3G网络很可能是TD-SCDMA与WCDMA混合组成的网络。本文基于TD-SCDMA能够与WCDMA（R99与R4版本）共享核心网的技术前提，综合业界提出的TD-SCDMA与WCDMA联合组网方案，分析了联合组网的可行性，对WCDMA和TD-SCDMA联合组网的优势，存在的问题以及不同组网方式进行了分析与探讨，并对两种系统共存时存在的干扰问题进行了仿真。

Feasibility study for the united networks of TD-SCDMA and WCDMA system

WCDMA and TD-SCDMA are mainstream standards of 3 generation communication system, they have different characteristic at transmit rate, united ways and symmetric/asymmetric traffic, so unite both of them and achieve best performance of network is a question that worth of investigating. The future 34 generation networks largely will may be based both on TD-SCDMA and WCDMA. The article according to the TD-SCDMA and the WCDMA（R99 and the R4 edition） Could share the core networks, and the field had proposed the plan of TD-SCDMA and WCDMA carried on unites the network. Analyzed the unite networks viewed on domestic TD-SCDMA and WCDMA . Mainly turns on the feasibility research and the isolation distance of the WCDMA base station to the TD-SCDMA system.
