N2 - The capacity of multiple antenna systems in the low-power regime has gained recently much attention [1]. It turned out that antenna correlation and Ricean factors do not have an impact on the Eb/N0min but on the slope in bits/s/Hz/(3dB). In this work, we analyze the impact of different types of CSI on the multiple antenna capacity in the low-power regime. We show that the Eb/N0min is reduced as well as the slope is increased by having channel knowledge at the transmit antenna array. The impact of spatial correlation on the two performance measures is completely characterized. Finally, the theoretical results are illustrated by numerical simulations showing the spectral efficiency over the received Eb/N0 for various systems.
