Abstract：MIMO-OFDM has been one of the most promising techniques for high data rate wireless transmission. In multi-user systems, how to guarantee the fairness among users while achieving large system throughput is an important issue for practical system design. In this paper, the Dirty-Paper Coding (DPC) as a new transmission technique is investigated to achieve the large throughput of MIMO systems, and a novel resource allocation algorithm based on Nash fairness is proposed for dirty-paper coded multi-user MIMO-OFDM systems. Simulation results show that the proposed algorithm can provide fair resource allocation among users, with less overall system rate loss.
