Abstract:
Improving efficiency of upcoming vehicle communication networks is one of the main goals in near-future wireless systems. In addition, multi-antenna configurations are known as the main technique to improve the system performance with current constrains, such as the limited spectrum. They are an unlimited and non-lasting resource, but they imply a more complex implementation. In this context, the design of this type of geometries must be optimized considering the entire scenario and the final propagation conditions. Due to the relation between the propagation environment and the correlation between elements, the antenna inter-element spacing has to be adjusted to reach the maximum performance at the minimum possible footprint size. This work investigates the impact of correlation on channel capacity and also proposes a proper separation of the elements when they are mounted on a vehicle for two different urban scenarios: communication between two vehicles (V2V) and car connected to the cellular network (V2I).
