This paper describes the enhancement of a deterministic propagation model to take into account essential elements of the urban environment in small cell configurations. For lower antenna heights lots of interactions of the electromagnetic waves occur with urban furniture and vehicles. Coupled to diffuse scattering and urban furniture models, the output of channel wideband characteristics from a deterministic...
The paper presents a method to introduce the diffuse scattering into a deterministic 3D ultrawideband indoor simulator. The purpose it to enrich the wideband channel model with more phenomena inserted as pseudo-stochastic parameters. The model predicts the field strength as well as the specular contributions of the impulse responses, and then the diffuse scattering, which are all essential in the...
The paper reports a method to introduce the diffuse scattering into a deterministic 3D ultrawideband indoor simulator. The implementation method is discussed and the chosen parameters impacting the diffuse scattering are explained. The prediction model estimates the field strength and the impulse response. A simple example: propagation along a corridor supports the discussion on the comparison between...
The paper presents an implementation of the diffuse scattering within a 3D urban propagation simulation method, based on ray-launching. New contributions representing the diffuse scattering are added to the traditional specular rays, leading to a more realistic model, especially when radio terminals are in the close vicinity of buildings. The impact of this enrichment on the simulated wideband propagation...
