WebThis was the script we used to generate the data for the Riverbed Modeler case study described in Section VI.A of the paper. example_stat_channel_model: this script generates a statistical channel model for a specified pair of source-receiver positions described in Subsection V.C. It also produces the graphs from Fig. 17 and 18. WebMar 18, 2024 · Implementation in 3D. During the initial ray tracing the angular resolution is set to Δθ = 30° in elevation and Δϕ = 36° in azimuth leading to 62 rays in total. For this step only, the time step size Δt for solving the ODEs is increased by a factor of 10 reducing the computational effort.. While tracing a ray, its distance to the receiver is tracked during …
