Ítem Delay spread in mmwave bands for indoor using Game Engines 3D Ray based Tools(Institute of Electrical and Electronics Engineers Inc., 2016-04-10) Cruz, WilliamSimulation results of channel parameters using a Game Engine Ray Based Tool in different operating systems with different hardware architectures and using an open source 3D modeling tool for an indoor scenario are presented in this paper. We present simulation results and compare them with a set of measurements for an indoor scenario in the 5.4 GHz band, obtaining good matches between the rays traced by the tool and measurements for delay spread.Ítem Prediction of Delay Spread Using Ray Tracing and Game Engine Based on Measurement(Institute of Electrical and Electronics Engineers Inc., 2015-05-11) Gomez, JorgeIn this paper, we show results of channel delay spread estimation using a 3D ray launching tool based on Game Engines and GPU, comparing simulation results with channel measurements of a MIMO system taken in Ilmenau. We show that the accuracy of the simulation is strongly affected by the ray angular separation in the first and second diffraction, obtaining a good fit between measurements and simulation.Ítem Comparison of Uniform Theory of Diffraction Coefficients for Delay Spread and Angle Spread Estimation Using Game Engines in MIMO(Institute of Electrical and Electronics Engineers Inc., 2015-09-06) Guevara, DinaelIn this paper, we show the results of the comparison between two different sets of heuristic uniform theory of diffraction (UTD) coefficients and its influence on the results for delay spread and angle spread. We compared our simulation results with measurements in an outdoor environment, showing the influence of the UTD coefficients in the accuracy of the results. The proposed coefficients show a better behavior than a classical set of coefficients widely used in literature.Ítem 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 JoanThe 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.
