Capacity considerations for wireless MIMO channels

Recently, capacity studies for wireless multiple-input multiple-output (MIMO) channels have been performed. Significant gains have been forecasted for relatively high signal-to-noise ratios when using multiple antenna elements at both the transmitter and the receiver. However, most of these results have been obtained under antenna independence assumptions. In this paper, further insights on the effect of realistic antenna correlation values for small antenna spacings as a function of angular spread are provided. A spatial multipath model suitable for computer simulation is proposed in order to quantify the achievable performance in presence of arbitrary antenna correlation. Results for different angular spread scenarios and power allocation strategies are presented.
