Conventional geometric channel models (GCMs) were applied to narrowband nondirectional modeling. The main purpose of this paper is to provide a unified analysis on the spatial pattern of scatterer distributions in the E-space for wideband directional channels (WDCs). One advantage of this approach is the availability of analytical expressions relating signal properties in the respective domains to channel properties. A further virtue of this method is to exploit the geometric distribution of scatterers from a physical wave-propagation viewpoint. The analysis is based on the recently proposed semi-geometrically based statistical (SGBS) model and four heuristic rules, which are so formulated as to provide the underlying relationship between the canonical model and the physical channel it represents. Finally, a layered multiple-input-multiple-output channel model is proposed by applying the generic methodology.
