TL;DR: This paper provides an overview of the state-of-the-art radio propagation and channel models for wireless multiple-input multiple-output (MIMO) systems and describes a couple of key features of channels and radio propagation which are not sufficiently included in current MIMO models.

TL;DR: In this paper, the results of a measurement campaign aimed at determining the far-field diffuse scattering pattern of typical building walls are shown in the paper, which are then used to determine and tune simple diffuse scattering models based on the effective roughness approach, to be embedded into ray tracing simulators.

TL;DR: In this article, a simple ray-based model is used to integrate reflection/diffraction with diffuse scattering to obtain good narrow-band and wide-band results with a low number of interactions.

TL;DR: A 3-D ray tracing model is used as a propagation-prediction engine to evaluate performance in a number of simple, reference cases and Ray tracing itself is proposed and evaluated as a real-time prediction tool to assist future BF techniques.

TL;DR: In this paper, a simple diffuse scattering model based on a ray approach suitable for urban radio propagation is presented, arranged so that the main parameters, having precise physical meaning, can be easily tuned using measurement results.
