<P>Abstract : A power allocation scheme for multi2user multiple2input multiple2output orthogonal frequency division multiplexing (MI2<BR>MO2OFDM) systems with channel state information (CSI) on transmitter and receiver is presened. Multi2user power allocation can<BR>be decoupled into single user power allocation throughout null space mapping of multi2user channel and power allocation can be per2<BR>formed throughout spatial2spectral water2filling for per user. To deal with more users in system and fading correlation , scheduling is<BR>performed to maintain the gain of power allocation. The proposed scheme can substantially improve system’s spectral efficiency with<BR>low complexity. Simulation results validate the accuracy of theoretic analyses.<BR>Key words : power allocation , multi2user information theory , radio resource management , MIMO , OFDM.</P>
