Okumura-Hata传播预测模型的可视化仿真研究

摘要

The paper presented a graphical modeling and visualizationcomputing approach for large-scale propagation models. It simulated the whole process of Okumura-Hata propagation model from modeling, experiment to analysis in a graphical environment by use of visualization computing techniques, and builded a visual simulation frame. It is programming free and among the simplest and best in terms of accuracy in path loss prediction for cellular and land mobile radio systems in graphical environments.%对大尺度传播预测模型的可视化计算问题进行了研究。应用先进仿真技术，通过对图形建模涉及的多种资源如算法、参数及结果数据等进行可视化处理，构造出Okumura-Hata传播预测模型的可视化计算环境。与基于传统高级程序设计语言(如C、Fortran)的数值预测方法相比，该方法不仅实现了Okumura-Hata模型的图形建模和可视化预测，而且无需算法编程及调试，为蜂窝和陆地移动无线通信路径损耗预测提供一个全面的图形化解决方案。
