Research on non-stationary characteristics under large-scale multi-antenna vehicle occlusion conditions

Abstract

The radio wave propagation characteristics of the wireless channel directly affect the transmission rate and transmission quality of the wireless communication system, so it is considered to be the basis of wireless communication system design. The mode of direct communication between vehicles belongs to the low delay sensitive communication type. Channel measurement is carried out under the condition that the link is blocked by other vehicles in the process of vehicle-to-vehicle communication, and the fading characteristics and delay characteristics of vehicle-to-vehicle occlusion are analyzed under different occlusion conditions. Then, a characterization method of channel time non-stationary characteristics in vehicle-to-vehicle communication is proposed, and the relationship between non-stationary characteristics and fading characteristics under vehicle occlusion is analyzed.
