Abstract

In order to accurately evaluate spatial processing techniques such as adaptive array antenna and MIMO techniques for wideband mobile communications, we require a time-spatial propagation model which allows the delay profile and spatial arrival angular profile characteristics of the travelling wave to be analyzed at the same time. In this paper, we propose an empirical time-spatial propagation model based on a heuristic formula estimated from field measurement data obtained in urban and suburban areas.
