摘要 该文在研究了多用户MIMO-OFDM系统中的动态资源分配问题的基础上,提出了一种MIMO-OFDM系统中以获取最大系统吞吐量为目标的新的动态资源分配算法。该算法在满足用户QoS需求的基础上,充分利用多用户分集特性,使系统对空-频二维资源和发送功率进行了有效利用,从而使系统的吞吐量得到了大幅度提高。仿真结果表明,该算法具有良好的性能,能够有效提高系统的吞吐量。 A QoS guaranteed dynamic resource allocation algorithm for downlink MIMO-OFDM systems is proposed based on the research on the issue of resource allocation in multiuser MIMO-OFDM systems. The proposed algorithm utilizes efficiently the spatio-frequency and power resources by taking full advantage of the multiuser diversity under the condition that the QoS requirements are guaranteed. So the system throughput is enhanced significantly. The simulation results demonstrate that the proposed scheme has good performance and can effectively enhance the system throughput.
