摘　　要：提出了一种基于MIMO/OFDM系统的空间子信道分配算法,在多用户环境下,以获取最大的系统吞吐量为目标,兼顾用户之间资源分配的公平性原则,充分利用系统的空间子信道资源,在保证发射功率恒定和一定的误比特率约束条件推导了多用户子载波分配准则,并给出了相应的算法流程.仿真结果表明,本算法具有良好的性能,既有效地提高了系统的吞吐量,又保证了用户之间资源分配的公平性.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.
