摘要
对多用户"多入多出-正交频分复用"(MIMO-OFDM)系统的空间子信道分配算法进行了研究,提出了使系统吞吐量最大化并且满足用户速率最小要求的多用户无线资源调度算法。仿真结果表明,与波束形成相比,所提算法具有更好的性能,既充分利用空间子信道,提高了系统容量,又采取有效措施保障了用户的公平性。
Spatial subchannels in multiuser Multiple Input Multiple Output/Orthogonal Frequency Division Multiplexing(MIMO/OFDM) systems are investigated.A wireless resource scheduling is proposed to make the throughput maximize while rate request is satisfied.The simulation results show that the proposed algorithm achieves better performance than beam-forming.The capacity is improved through using spatial subchannel efficiently,and the fairness of users is also effectively protected.
