Time-space path model in wide-band mobile communications

In order to estimate accurately spatial processing techniques such as adaptive array antenna and space diversity techniques in wideband mobile communications, the time-space path model in which both characteristics of the delay profile and of the spatial arrival angle profile for traveling wave can be analyzed at the same time is required. In this paper, we propose a static time-space path model taking the arrangement of buildings in the city part into account and a dynamic time-space path model considering the movement of the mobile station. We show that the analysis using the dynamic time-space path model well agrees with the field measurement results.
