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: 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: An overview of ray tracing propagation modeling is given in this article, with a special attention to future prospects and applications, such as extension to diffuse scattering, multidimensional channel characterization, multiple-input multiple-output (MIMO) capacity assessments, and future applications such as real-time ray tracing.

TL;DR: Two different classes of methods for speeding up ray tracing urban field prediction are proposed, aimed at reducing the size of the input database and the number of rays to be handled by the algorithm.

TL;DR: The proposed semi-deterministic channel modeling approach by associating the scatterers with realistic environment objects, and by calculating the coefficients of the propagation paths on the base of a physically sound and proven diffuse scattering theory can accurately predict the channel characteristics in both the delay domain and the angular domain.
