There is a growing research interest in massive Multiple Input Multiple Output (MIMO) antenna systems because of their higher channel capacity and energy efficiency. New applications in digital mobility and connected car is certainly one of the areas of future development of these systems. In order to study the impact of the different multi-antenna geometries and MIMO modalities in both the vehicle and the fixed base station, a quality modeling of a realistic scenario is needed. In this paper, study of initial antenna configurations for both — mobile and fixed — platforms is performed and initial channel parameters and system capability are obtained. Then, several systems and constellations are compared by means of the channel eigenvalues and capacity. The analysis is based on the results of a simulated model of an urban scenario, emulating as a case of study a portion of the city of Barcelona in a realistic environment, comprising of a massive MIMO base station and a car at various positions.
