Abstract: In this paper,we mainly discussed multi-user MIMO-OFDM in order to provide a fair network resource allocation for each user.Firstly we provided a brief introduction of MIMO-OFDM model,then we introduced the utility function.Secondly we discussed how to allocate resources,and here we focused on how to allocate sub carries to each user and how to allocate entire power to each subcarry.Finally,we gived our simulation results and analyzed the performance.

Key words: MIMO, OFDM, sub carries allocation, power allocation

摘要: 论文主要考虑多用户的MIMO-OFDM问题,以使得各个用户更公平有效地分配网络资源。文章首先给出MIMO-OFDM模型,然后引入反映用户满意程度的效益函数,并给出在MIMO-OFDM模型下的效益函数具体形式。其次,进行资源分配,重点考虑OFDM的各个子载波该分配给哪个用户,以及总功率该如何分配给各个子载波,从而实现系统的最优化。最后,文章给出了仿真结果,并着重对仿真结果进行了详细的性能分析。
