“…As support for the UMi measurements, RT simulations were performed for the OS-CC and SC-CC environments. The polarimetric RT tool, which has been developed by the Fraunhofer Heinrich Hertz Institute (Berlin, Germany) based on NVIDIA’s OptiX engine, makes use of parallelized processing on the graphics processing unit (GPU) [ 27 ]. It applies geometrical optics (GO) and the uniform theory of diffraction (UTD) for reflections on convex surfaces.…”

In order to support the development of channel models for higher frequency bands, multiple urban microcellular measurement campaigns have been carried out in Berlin, Germany, at 60 and 10 GHz. In this paper, the collected data is uniformly analyzed with focus on the path loss (PL) and the delay spread (DS). It reveals that the ground reflection has a dominant impact on the fading behavior. For line-of-sight conditions, the PL exponents are close to free space propagation at 60 GHz, but slightly smaller (1.62) for the street canyon at 10 GHz. The DS shows a clear dependence on the scenario (median values between 16 and 38 ns) and a strong distance dependence for the open square and the wide street canyon. The dependence is less distinct for the narrow street canyon with residential buildings. This behavior is consistent with complementary ray tracing simulations, though the simplified model tends to overestimate the DS.

“…The OptiX Ray Tracer is a polarimetric parallel ray tracing simulator developed by the Fraunhofer Heinrich Hertz Institute based on NVIDIA's OptiX engine [3]. This tool uses ray forward tracing and backward tracing via the imaging method to efficiently and accurately compute the radio channel for a given scenario [3]. The common imaging method has been extended to support reflections via curved surfaces.…”

In this paper, the influence of tree trunks, cylindrical street furniture such as lamp posts, and traffic on ray tracing simulations in an urban scenario is analyzed. Tree trunks and lamp posts are modeled by cylinders and propagation characteristics computed according to the Uniform Theory of Diffraction. The influence of traffic is analyzed by simulations with moving vehicles. In order to get an understanding of the spatial characteristics of the channel, simulations with static and also mobile receivers have been performed, in line with a measurement campaign in the same environment. The simulation results show a good agreement with the measurements

“…Generally, this enhancement can be achieved by the combination of ray tracing with some accurate full wave solvers (such as FDTD [6]) in regions of the problem where the ray approximation model does not hold. As for the speed, it can be significantly improved by optimizing the algorithm implementation on GPU hardware [7].…”

In this paper a generic 2D Ray tracing channel modeling tool is proposed. The proposed tool has been optimized for GPU architecture. Two examples for different types of applications have been presented and used to profile the tool. Comparative results have been presented for different parameters and examples. Due to its high speed, the proposed tool is useful for system optimization for large EM problems such as automotive radar application.
