Abstract
In 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.
