From broadband ray tracing propagation modeling to physical layer simulations of THz indoor communication systems

2013 IEEE Radio and Wireless Symposium, 2013
Allowing for the conception of future THz indoor communication systems, a simulation environment combining an accurate ray tracing propagation model as well as a physical layer simulator is introduced. Frequency domain ray tracing is demonstrated for a wireless LAN setup in an indoor environment at frequencies from 300 to 350 GHz.

Accurate Simulation of Wireless Vehicular Networks Based on Ray Tracing and Physical Layer Simulation

2012
Vehicle-to-vehicle (V2V) and vehicle-to-roadside (V2R) communications is required for numerous applications that aim at improving traffic safety and traffic efficiency. As recent studies have shown, communications in this context is significantly influenced by radio propagation characteristics of the environment and the signal processing algorithms ...

Low Grazing Angle Sea Clutter modelled by Ray Tracing and Physical Optics

2000
In this project we study radar scattering from the sea surface in a number of ways. We generate 3D realisations of the sea surface and models of breaking waves. These objecs are put in CAD format. A ray tracing algorithm is used to calculate the illumination of the object and the local incidence angle of the radiation. Based on these results a physical

Ray Tracing Simulations of Indoor Channel Spatial Correlation for Physical Layer Security

2015
The goal of this work is to establish the accuracy of ray tracing to simulate the radio channel in a Physical Layer Security scenario, where two legitimate users try to take advantage of the intrinsic properties of the channel to generate a shared secret key inaccessible to an eavesdropper.
