摘要


随着4G移动通信的飞速发展,利用信道模型进行网络规划成为研究重点.在云南省复杂传播环境下,选取了农村密集型和农村开阔型2种典型传播环境来研究信道特性.信道模型采用室外传播模型——Okumura模型.首先在这2种环境下进行数据采集、加工,接着利用Okumura模型对环境进行仿真,并与实测数据进行比较,最后得出结论:在2种环境下修改Okumura模型的参数,可以达到对传播特性预测的目的. With the rapid development of 4G mobile communication, the channel modeling for network planning has become a research focus. With a consideration of the complex transmission environment of Yunnan province, this paper studies two kinds of typical communication environments, the rural intensive and rural extensive types, as well as their channel characteristics. The Okumura model as an outdoor transmission type is used for data acquisition and processing, and then, the simulation is carried out and compared with the in-situ data. Finally, it has reached the conclusion that the modification of the parameters of the Okumura model for different environments will help predict the transmission characteristics.
