摘要

本文介绍了建立三维全波室内传播模型的初步工作。该模型基于体积电场积分方程(VEFIE)，该方程通过弱形式离散得到密集线性系统，其解可以通过使用快速傅里叶变换和简化算子来加速。并与现有的室内波传播标准射线追踪法进行了比较。结果表明，两种模型非常吻合。

Preliminary comparison of 3D integral equation based indoor propagation model and ray tracing

This paper presents preliminary work done on developing a 3D full-wave indoor propagation model. The model is based on the volume electric field integral equation (VEFIE) which when discretised by a weak-form discretisation results in a dense linear system whose solution can be expedited through use of the Fast Fourier Transform and a reduced operator. A comparison between the current standard for indoor wave propagation, ray tracing, is made. Very good agreement between the two models is shown.
