In order to accurately estimate the performance of spatial processing techniques such as Adaptive Array Antenna (AAA) and Multi-Input-Multi-Output (MIMO) in wideband mobile communications, we require a time-spatial path model that allows the characteristics of the delay profile and those of the spatial arrival angle profile for traveling waves to be simulated at the same time. This paper explains an empirical time-spatial propagation model that we developed based on the measurement data on UHF and SHF bands. A part of results of this paper was standardized as ITU-R recommendation P. 1816. Furthermore in this paper, we propose a novel physical time-spatial propagation model using a simple ray tracing method and show it can explain the measurement results very well.
