预测室内电波传播的混合方法

The Hybrid Method for the Indoor Radio Wave Propagation Prediction

射线跟踪(RT)算法与时域有限差分(FDTD)法是对室内无线电波传播进行研究的有力工具。大多文献对此作有详细的探讨,而对于两者结合而形成的混合法则很少提及。本文对基于混合法的室内传播预测进行了详细的讨论,计算结果表明了该方法的有效性和准确性。

The Ray-Tracing and FDTD methods are very useful for studying the indoor radio wave propagation. There are many papers which study the two methods separately in details. However,a few papers study a hybrid method combining the Ray-Tracing one with FDTD one. This paper discusses a model using the hybrid method. The result show that the method is very useful and accurate.
