A Two-Dimensional Geometry-Based Stochastic Model
In this paper, the problem of deriving the Power Angular Scattering Response (PASR) resulting from a Gaussian scatterer distribution is undertaken. Differently from previous work, the scatter cluster can be located arbitrarily in the vicinity of the mobile unit. Furthermore, for the considered scatter geometry the authors derive both the angular and distance statistics at the observation point, allowing for the first time a theoretical characterization of PASR. A major byproduct of this analysis is that the Gaussian scatterer hypothesis is formally shown to produce a Gaussian power angular spectrum in a macrocell environment, which is in accordance with existing measurements.
