【摘要】 有效的设计、评估和安装室内无线网络需要准确地描述室内无线信道特性。在二维情形中,基于结合射线跟踪法和时域有限差分法(FDTD)的室内无线传播混合建模方法对于室内无线传播的预测结果与测量结果吻合较好。本文中,将这种混合建模方法拓展到三维空间中,以利对室内实际环境中电波传播的预测。更多还原

【Abstract】 The effective design, assessment, and installation of a radio network in an indoor environment require an accurate characterization of the radio propagation channel. In a 2-D structure, the calculation results of a hybrid method, which is based on combing ray tracing and finite-difference time-domain (FDTD) method, agree well with the measurement. In this paper, the hybrid method is extended to 3-D problems. It will be helpful to obtain the radio wave propagation prediction in indoor real environments.更多还原
