Delay spread estimation using a Game Engine Ray based model in indoor scenario at 5 GHz
(Asian Research Publishing Network, 2016-03-01) Escalante, Diego
In this paper we show the results of a simulation of channel parameters using a Game Engine Ray based tool, developed by our group, which has been evolving during last few years. We show simulation results and compare it with a set of measurements for an indoor scenario, in the band of 5.4 GHz. We found a good match between the rays based tool and measurements for Delay Spread. Also, we show the use of an Open Source 3D modelling tool for the scenario building, showing the flexibility of the XML description language for this kind of scenarios. © 2006-2016 Asian Research Publishing Network (ARPN).
Indoor Propagation Using a Game Engine Ray-Based Model in Indoor Scenario at 5.4GHz
(Institute of Electrical and Electronics Engineers Inc., 2016-05-15) Gimenez, Jordi Joan
The results of a simulation of signal propagation strength in indoor environment using a game engine ray-based tool and use of an open source 3D modeling tool for scenario building are presented in this paper, showing the flexibility of the XML description language for this kind of scenario. We show simulation results and compare them with an extensive set of measurements for an indoor scenario with multiple materials in the 5.4GHz band, obtaining a good match between the ray-based tool and measurements of received power. We found also that constitutive parameters have an important effect on the simulation results and made some small adjustments to improve results.
