LiDAR assisted ray-tracing for mmWave and THz channels
Ray-tracing simulation is an effective approach to study millimeter-wave and terahertz channels. It requires the geometrical properties of objects in the scenario, such as the locations and shapes of walls, tables, metal frames, etc. The channels are generated by considering the path components due to reflections, diffractions, and scatterings from these objects. One usual way to obtain the geometrical information of all the physical objects is to manually measure them with a meter, which is very time-consuming, cumbersome, and not accurate enough. Therefore, we aim to exploit a LiDAR (light detection and ranging) system to scan the scenario and output the scenario geometry in a fast and automatic way. The work involves getting the point cloud of the scenario, identifying and associating different objects, and transforming the point cloud to geometry data that can be used by the ray-tracer. Channel measurements and comparison of measured and simulated channels shall be done to verify the work. An advanced LiDAR system has been ordered and will be ready in February, and this project is expected to start in February – March earliest. This project will facilitate further investigations for mmWave and THz channel modeling and communications within a larger research project granted by the Physiographic Society of Lund. We welcome motivated students with a good background and knowledge of radio channels and related areas. Feel free to contact Xuesong Cai (firstname.lastname@example.org) for more information.
