摘要:

针对特定的无线环境和采用的频率,选择良好的传播模型是准确进行网络规划和优化的基础。在评述目前国内外基于LTE所采用的经验传播模型、半经验模型及确定性模型的基础上,对各类传播模型进行了分析与比较,并给出了相同条件下不同传播模型的衰减损耗对比。在此基础上,给出了LTE在密集市区场景下的传播模型选择建议。

Abstract:

The accurate network planning and optimization was based on good radio propagation model for the particular wireless environment and specific frequency.Several types of LTE-based propagation models were reviewed under the three kinds of propagation model such as empirical model, semi-empirical model and deterministic model. A comparison was made between different proposed propagation models that would be used for the LTE. Further, attenuation loss for the different propagation models under the same conditions was listed. Lastly, a good propagation model choice strategy for the TD-LTE in dense urban scene was presented.

Key words: LTE, empirical model, semi-empirical model, path loss
