跪求一篇关于TD_SCDMA无线网络规划的英文资料（带中文翻译的）

网络规划是TD-SCDMA移动通信系统规划最为关键的部分。无线子系统的投资通常能占到网络总投资的三分之二以上，其设计成败关系着整个移动通信网络建设的成败。TD-SCDMA网络规划包括传播模型选择，链路预算，容量规划，系统仿真，站点勘测，无线参数规划，频率和扰码规划等方面。 

Network planning for TD-SCDMA  system is  the key part of the wireless communication system design.  The investment for wireless subsystem can occupy two thirds of the total network capital. Network planning play an important role in the construction of the whole mobile network. Propagation Model seclect, link budget, capacity planning, system emulation, site survey, radio parameter planning, Frequency&CPI assignment are included in the TD-SCDMA network planning.
