传播模型是移动通信小区规划的基础。对于3G系统,传播模型的准确性,直接关系到运营商是否能以比较经济合理的投资,满足用户的需求。每一个模型都只是反映了特定地区的电波传播特性,事实上由于各个地区地物地貌有差异很大,必须对模型的参数进行修改,也就是需要进行模型校正。对3G传播模型校正方法进行分析研究,为下一阶段的网络建设及第3代移动通信系统的建网提供切实有效的参考依据。
The propagation model is the basis of mobile communication community planning. For 3G systems, the accuracy of the propagation model is directly related to whether operators can meet the needs of users with more economical and reasonable investment. Each model only reflects the radio propagation characteristics in a particular area. In fact, due to the large differences in the topography of various regions, the parameters of the model must be modified, that is, the model calibration needs to be performed. This paper analyzes and studies the method of 3G propagation model calibration, which provides an effective reference for the next phase of network construction and the third generation of mobile communication system.
