		<description><![CDATA[Motivated by the increasing popularity of OFDMA and MIMO, this paper studies the capacity of MIMO enabled OFDMA system under a generic multiuser multicarrier framework. This paper shows that in terms of total system capacity, OFDMA is the optimal downlink scheme for independent decoding receivers. To achieve the capacity bound...]]></description>
