摘　　要：笔者在研究LTE系统的基础上,利用最小二乘法对实测信号损耗数据进行预测,从而建立符合实际地形的信号传播模型,最后,根据校正后的传播模型,通过GIS仿真软件来分析路径损耗情况及可视化,从而为LTE网络规划和优化提供有价值的意见。On the basis of the study of the LTE system, the least square method is used to predict the measured signal loss data, so as to establish a signal propagation model which is in line with the actual terrain. Finally, according to the corrected propagation model, the path loss and visibility are analyzed by the GIS simulation software, thus the LTE network planning and optimization are proposed.

关 键 词：LTE 传播模型 GIS可视化
