NLOS-communication between shadowed vehicles using by-standing relay vehicles

We consider a dual-hop vehicle to vehicle (V2V) relay channel, where a source vehicle communicates with a destination vehicle using a third vehicle as a relay node. The inter-vehicle relay channel is the product of two independent fading processes generated by two independent groups of scatterers. A novel MMSE estimator is proposed for the aforementioned dual-hop relay channel. The fading process at each hop is modeled as Rayleigh fading as well as Nakagami-m fading. The latter is widely used for modeling severe fading in V2V channels.
