【Abstract】 A spatial subchannel allocation algorithm based on multiuser MIMO/OFDM systems was proposed to achieve the fairness and maximizing overall data throughput under multijser conditions.With the consideration of all the spatial subchannels,the criteria of subcarrier allocation was derived and the adaptive allocation approach was developed,while guaranteeing prescribed error performance,under the constraint of fixed transmit-power.The simulation results show that the proposed algorithm did not only achieves good performance and high total transmission rate efficiently but also guaranteed a fairness property.更多还原
