  Channel Modeling using QuaDRiGa (QUAsi Deterministic RadIo channel GenerAtor) and SE-NAV Ray-tracing Machine Learning based Non-Line-of-sight NLOS and LOS Multipath signal detection for 5G and GNSS Satellite using Python.Multipath severely harms the localization accuracy of GNSS and 5G signals. Through the study of channel models and simulation of real environments via Ray-Tracing we are able to accurately predict what kind of signal it is and further on allows mitigation of NLOS signals. In the end we are able to get close to centimetre level accuracy indoors where GPS hardly even works. Show less
