提出基于地物类型矢量距离的4G LTE传播模型选择方法,根据地物类型最小矢量距离,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选择方法得到的传播模型与该区域实测得到的传播模型进行覆盖预测仿真结果对比,证明多维加权矢量距离选择方法可靠性最高,对4G LTE网络精细化规划和工程建设具有实际指导意义.%A selection method of 4G LTE propagation model based on landform vector distance was proposed in this paper, in which a proper propagation model can be selected according to landform minimum vector distance for the scene without continuous wave test calibration. By comparing the propagation model derived from two-dimensional unweighted, two-dimensional weighted and multidimensional weighted methods with the propagation model derived from real tested data, the coverage simulation results show that, the method based on multidimensional weighted vector distance is the most reliable which has guiding signiifcance to ifne planning and engineering construction of 4G LTE network.
