基于地物类型矢量距离的TD-LTE无线传播模型映射方法

受限于CW测试工作量和目前各主要频段都已经在使用的无线传播环境条件,无法对每个城市、每个场景进行无线传播模型校正.本文提出基于地物类型矢量距离的TD-LTE无线传播模型映射方法,即根据地物类型最小矢量距离的映射关系,为无CW测试校正的城市或场景选取合适的传播模型.通过对二维不加权、二维加权和多维加权进行ANPOP仿真对比分析,证明多维加权矢量距离映射方法可靠性最高,对精细化网络规划和工程建设具有实际指导意义.

Research on method of TD-LTE propagation model mapping based on vector distance which is depended on the landform

As most of the main frequency resource of LTE is being used and the propagation model adjustment is amount of work, it is difficult to make an adjustment for every city or scene. A propagation model mapping method based on vector distance which is depended on the landform for non-adjustment city or scene is pushed out. Through the ANPOP simulation analysis of two -dimensional without weighting, two-dimensional with weighting, multi-dimensional with weighting, the performance of multi-dimensional with weighting is most reliable. It is a significant way for making a network fine planning. Constructions can be guided by it as well.
