| 摘 要： | 根据室内电波传播的特点，对室内电波的反射，透射和绕射等传播路径进行了分析，首次考虑了多层介质的反射，透射以及棱角边缘的绕射，建立了基于射线跟踪法的二维和三维传播预测模型，根据这些模型能够计算出室内各处电波传播的路径损耗。计算结果与测量结果符合很好。同时，将二维和三信跟踪预测结果作了比较，结果表明在有些情况下二维跟踪更经济实用。

| Abstract: | In this paper, reflection and refraction of multilayer and diffraction by edge in indoor environments are analyzed for wireless communications.Raytracing algorithm of propagation prediction based on GO(Geometrical Optics)and UTD(Uniform Theory of Diffraction)is presented.A software that can give the path loss of any site inside the building has also been developed.The results agree well with measurement.The comparison between 2 and 3dimensional (2D and 3D)ray tracing indicates that sometimes 2D model is more economic and practical. |
