Abstract :
In order to accurately evaluate spatial processing techniques such as MIMO for wideband mobile communications, a Time-Spatial Propagation (TSP) model that can simulate the characteristics of both the delay profile and the spatial arrival angular profile for travelling waves at the same time is required. We proposed an empirical TSP model for wideband mobile communication systems using UHF and SHF bands in non-line of sight (NLOS) environments. Based on field measurement data, this paper extends the TSP model for NLOS environments to also cover Line of Sight (LOS) environments.
