A 3D geometry-based scattering model for vehicle-to-vehicle wideband MIMO relay-based cooperative channels

In this paper, a three-dimensional (3D) geometry-based stochastic scattering model (GBSSM) for wideband multi-input multi-output (MIMO) vehicle-to-vehicle (V2V) relay-based cooperative fading channel based on geometrical three-cylinder is proposed. Non-line-of-sight (NLOS) propagation condition is assumed in amplify-and-forward (AF) cooperative networks from the source mobile station (S) to the destination mobile station (D) via the mobile relay station (R). We extend the proposed narrowband model to wideband and also introduce the carrier frequency and bandwidth into the model. To avoid complicated procedure in deriving the analytical expressions of the channel parameters and functions, the channel is realized first. By using the realized channel matrix, the channel properties are further investigated.
