Introduction of diffuse scattering to enhance ray-tracing methods for the analysis of deterministic indoor UWB radio channels (Invited Paper)

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 performance estimation of new radio systems (diversity, MIMO).
