Utilization of the V2X Radio Channels Temporal Stationarity for Communication and Radar Sensing

In this paper, we discuss the possibilities of utilizing the stationarity of the vehicle to everything (V2X) radio channel for applications in the field of communication as well as passive radar. The stationarity can be interpreted as a measure of how severely the radio channel changes. We compute it in the temporal domain using the generalized local scattering function (GLSF) and its collinearity. Knowing about the stationarity can enable us to adapt communication and passive radar systems to make them more efficient and reliable at the same time.
