Time-space path modeling for wideband mobile propagation

In order to estimate accurately spatial processing techniques such as adaptive array antenna and space diversity techniques in wideband mobile communications, we require the time-space path model in which the delay profile and spatial arrival angle profile characteristics of a traveling wave can be analyzed at the same time. We propose a new time-space path model expanding the ordinary scattering model and show that the proposed model explains well the field measurement results of both the arrival angle distribution and the delay time distribution in the urban area.
