The well-known assumption of horizontal plane wave propagation is investigated and evidence suggests that elevation plays a crucial role in defining the spatial correlation between signals on adjacent antenna array elements. To augment previously published studies, an explicit relationship between the distribution of scatterers in three-dimensional (3D)(More)
In this paper the long standing problem of a heavy tailed power azimuth spectrum and the associated scattering mechanism that triggers its observance is undertaken using the geometry-based stochastic approach that was initially developed in [1], and is further extended herein. More specifically, the unimodal power azimuth spectrum (PAS) and joint power(More)
In this paper, the angular power spectrum exhibited under a three-dimensional (3-D) Gaussian scattering distribution at fixed observation points in space is investigated. Typically, these correspond to the mobile and base units, respectively. Unlike other spatial channel models, the derived model accounts for the distance to each scatterer from the(More)
