| 摘 要： | 文章对Okumura-Hata模型、COST231一Hata模型、Egli模型三种电波传播模型进行了简要分析。通过对某地的电波传播损耗进行测量得到实测数据，与预测模型仿真结果进行对比分析，对比结果显示COST231一Hate模型与实测值最接近，并且通过对COST231一Hate模型的修正，使得修正后的模型满足高精度电波传播模型的6dB要求，适合用于预测本地的电波传播。

| Abstract: | Three radio wave propagation models:Okumura-Hata Model,COST231-Hata Model and Egli Model,are firstly presented in this article.On-site test propagation loss data are used to get simulations on these models,simulation results and actual data are then compared,results show that COST231-Hata Model has narrower error band.This article lastly modifies COST231-Hata Model,to make the modified model has even higher accuracy 6dB when applied to the prediction of local radio propagation. |
