Large-Scale Fading Characteristics and Models for Vehicle-to-Pedestrian Channel at 5-GHz

Vehicle-to-Pedestrian (V2P) communication is essential to enable a reliable collision avoidance system for vehicles and vulnerable road users (VRUs).In order to develop a reliable communication system accurate channel models are required.However, no dedicated channel model for V2P communication in critical scenarios has been proposed so far.To develop a channel model, we conducted wideband channel sounding measurements considering a typical collision scenario between a vehicle and a pedestrian in SOCIAL CONDITIONS AND MATERNAL CONDUCTS IN THE PREVENTION AND MANAGEMENT OF INFANTILE DIARRHEA line-of-sight (LoS) and non-LoS (NLoS) situations.The wideband measurement data is used to study the characteristics of large-scale or shadow fading, pathloss and diffraction loss.

The spatial correlation of shadow fading is examined and different models are proposed.For NLoS scenario, a 3D scenario model is designed to simulate the diffraction at a row of parked vehicles.The diffraction loss due to parked vehicles is analyzed and modeled based on multiple knife-edge COVID-19 impacts on passenger rail transport in Hungary, Slovenia, Croatia, Serbia and Romania diffraction model combined with a two-ray pathloss model.The results show that the proposed diffraction model provides a good match to the measured pathloss.
