Abstract

Capacity increases promised by Multiple-Input Multiple-Output (MIMO) systems mostly depend on the spatial correlation properties of the radio channel. This paper investigates the connection between these properties and the capacity figures. It first derives the correlation coefficient between two antenna elements as a function of their spacing, the Power Azimuth Spectrum (PAS), the Azimuth Spread (AS) and the mean angle of incidence of the waves, for three different types of PAS, namely uniform, truncated Gaussian and truncated Laplacian. With the help of the established relations, correlated flat-fading MIMO channels are generated, whose capacity performance and Effective Degrees Of Freedom (EDOF) are investigated for two power allocation schemes, water-filling and uniform. The impact of channel estimation errors is also evaluated.
