Abstract :
MIMO systems, employing array of antennas at both ends of the transmission link, provide significant increase in the achievable capacity. The ability to achieve this high capacity is greatly influenced by the geometry and dimensions of antenna array used and the correlation between the channel gains on each antenna element in the array. In this paper, the expression of capacity, derived from information-theoretic approach is altered to introduce the impact of antenna array on the system capacity. Using this expression, capacities with different antenna array geometries are compared. The influence of different array configurations on system capacity is modelled by using `array manifold vector´ in the expression of channel matrix.
