摘要：
Subcarrier and antenna allocation is one of most important issue for multiuser MIMO-OFDM systems radio resource management. In this paper; a suboptimal subcarrier and antenna allocation algorithm with less complexity is proposed, based on the analysis of optimal antenna and subcarrier allocation algorithm. Numerical results show, that there is only a little performance deterioration on capacity upper bound with the proposed algorithm compare to optimal algorithm, and multiuser diversity is also exploited simultaneously by the allocation algorithm in multiuser environment.
