abstract

• This paper presents a geometry-based statistical model (GBSM) of polarimetric wideband multipath radio channels for vehicle-to-vehicle (V2V) communications. The proposed model captures the effects of depolarization caused by multipath propagation, and it also accounts for the non-stationary characteristics of wideband V2V channels. This is a novel feature, because the existing polarimetric channel models are built on the assumption that the channel is a wide-sense stationary random process. In the modeling framework described in this paper, the channel depolarization function is given by a linear transformation in the form of a simple rotation matrix. This linear transformation is transparent to the polarization of the transmitting and receiving antennas, and to the geometry of the propagation scenario. Compared to other GBSMs for polarimetric V2V channels, the one proposed here is more flexible, and it simplifies the computation of the channel depolarization function. © 2019 IEEE.
