%X MIMO/OFDM is an effective architecture for future wireless communication systems. A spatial subchannel allocation algorithm based on mean feedback model over multiuser MIMO/OFDM systems is proposed in this paper. With the goal of maximizing overall data throughput the criteria of subcarrier allocation is derived and the adaptive allocation approach is developed. The simulation results show that the proposed algorithm can efficiently achieve good performance and high total transmission rate.
