A three-dimensional ray-tracing model for the use of the uniform theory of diffraction and geometrical optics in radio channel characterizations of indoor environments is presented in this paper. Based on the environment information chosen by the proposed modeling approach, the model is effectively applied by utilizing a technique in which multiple reflections, transmissions, and diffractions are considered via the ray-path classification into four different categories. Ray paths belonging to each ray category are determined by using different methods. Our theoretical results are compared with narrowband and wideband measurements. The good agreement with these measurements indicates that our prediction model works well for such indoor communication applications.
本文提出了一种三维射线追踪模型,用于在室内环境的无线信道表征中运用一致性绕射理论和几何光学。基于所提出的建模方法选择的环境信息,该模型通过一种技术得到有效应用,该技术通过将射线路径分类为四种不同类别来考虑多次反射、透射和绕射。属于每个射线类别的射线路径通过不同方法确定。我们的理论结果与窄带和宽带测量结果进行了比较。与这些测量结果的良好一致性表明,我们的预测模型适用于此类室内通信应用。
