In this paper, closed-form expressions for capacities per unit bandwidth for spatially correlated multiuser MIMO-OFDM systems employing Orthogonal Space-Frequency Block Coding (OSFBC) over multipath frequency-selective fading channels are derived for optimal power and rate adaptation, optimal rate adaptation with constant transmit power, channel inversion with fixed rate, and truncated channel inversion adaptation polices. A Signal to Noise Ratio (SNR) based user selection scheme is considered. Closed-form expressions are derived for spatially correlated OSFBC-OFDM system. Optimal power adaptation policy provides the highest capacity over the other adaptation policies.
