This study aimed at the development of the standard spatio-temporal channel model for indoor and outdoor environments. Two approaches are taken for the purpose : the spatio-temporal channel sounding that measures the spatio-temporal channel parameters in the real environment, and the ray-tracing simulation that predicts the channel properties based on the building database. Both approaches separate the channels into geometrical paths and estimate the directions of departure and arrival, delay time, doppler frequency, and path gain. Statistical behavior of these paths are focused in the study to obtain the standard channel model.The ray-tracing simulator has been validated in the suburban microcell, urban microcell and indoor environments by comparing with the experiments. A new method has been developed to treat the case when the road and the direction of arrival are close to parallel.The spatio-temporal channel sounder has been expanded to the multiple-input multiple-output (MIMO) architecture, and the prototype has been fabricated at 2.45 GHz for the test operation. Simultaneously, another simplified channel sounder using a vector network analyzer and an antenna position controller has been built. It has been used for the indoor and short-range wireless channels to find the geometrical paths. It has been also used to study the non-specular scattering from the wall surface.

这项研究旨在开发用于室内和室外环境的标准时空通道模型。出于目的，采用了两种方法：在真实环境中测量时空通道参数的时空通道声音，以及基于构建数据库的通道属性的射线追踪模拟。两种方法都将通道分为几何路径，并估算出发和到达，延迟时间，多普勒频率和路径增益的方向。这些路径的统计行为集中在研究中，以获得标准通道模型。通过与实验进行比较，已在郊区的Microcell，Urban Microcell和室内环境中验证了射线追踪模拟器。当道路和到达方向接近平行时，已经开发了一种新方法来治疗案例。时空通道声音已经扩展到多输入多输出（MIMO）体系结构，并且原型在2.45 GHz中用于测试操作。同时，已经构建了另一个使用矢量网络分析仪和天线位置控制器的简化通道音响器。它已用于室内和短距离无线通道，以找到几何路径。它也被用来研究壁表面的非特定散射。
