WCDMA无线传播模型校正

基于WCDMA移动通信网络,讨论了传播模型校正的单变量校正方法和多变量校正方法,基于Matlab/Simulink图形化仿真工具,采用模块化动态分析组合方法,提出了对传播模型建立标准模型库的设计思想.利用图形化界面分析,对典型的传播模型进行对比,所建立的Simulink图形化仿真工具包能满足实测、分析校正的要求.以某地实测为例,结合Planet网规软件,详细阐述了无线传播模型参数校正的操作流程、结果分析,并给出了校正后预测值与实测值的对比分析,实现了无线传播模型的校正和网络优化.

WCDMA Wireless Propagation Tuning

Based on WCDMA mobile communication system, single variable tuning and multi-variable tuning for propagation model are introduced.Then according to the graphic tools of Simulink and Matlab,the modularization dynamic method is adopted and the idea of creating standard library for propagation model is put forward.Based on the graphic interface analysis,one representative propagation model has been deeply analyzed and compared,and the tool packets meet the requirements of real testing and tuning.In the end,taking one real testing for example,using software of Planet,operation flow and result analysis in the area of the tuning of wireless propagation parameters have been expounded in detail.The contrast analysis between forecasting value and real testing value has been demonstrated after the tuning,and the tuning of wireless propagation model and the optimization of network have been realized.
