To study the performance of the multi hop MIMO in case of V2V and V2I, which type of channels are required to model? Is there any standard channel model for multi hop MIMO?
i think the model used for multi-hop MIMO relay networks would be applicable for V2V and V2I simulations. The main differences would be that for V2V communications you have to consider a moving relay or a number of relays and the appropriate channels between them. Similarly for V2I the relays would be considered fixed.
