- Abstract
- Stochastic geometry-based models have been widely adopted for modeling wireless channels. These models are parametrized based on extensive measurement campaigns, where individual propagation paths are extracted with algorithms like SAGE or RiMax. It has been observed that when extracting individual propagation paths, part of the power is not captured. This residual power is referred to as the diffuse multipath component (DMC). In this paper, the spatio-temporal characteristics of the DMC are extracted from an extensive measurement campaign. It is observed that the angular power spectrum of the DMC is not angular-white, and that the angular properties of the DMC are significantly correlated with the angular properties of the specular part of the channel. A scheme is proposed to model the diffuse part of the channel by adding diffuse properties to each cluster corresponding to the specular part of the channel. The angular properties of the diffuse part of the clusters are modeled with Von-Mises distributions, whereas the delay properties of the clusters are modeled with an exponential decaying power profiles. Finally, the polarization properties of the diffuse part of the clusters are investigated.
