摘　　要：提出了一种多用户MIMO OFDM系统中基于合作博弈模型的资源分配算法,该算法在满足每个用户的最大发送功率、最大和最小传输速率需求的基础上获得了纳什讨价还价解,使系统的收益达到最大,并满足了用户的公平性要求。仿真分析表明:该算法获得的系统吞吐量略逊于Max-Rate方案,但用户公平性明显优于Max-Rate方案,能够在系统吞吐量和用户公平性之间获得较好的折衷。A resource allocation algorithm based on cooperative game model was proposed for the downlinks of multi-user MIMO-OFDM systems. The proposed algorithm exists Nash bargaining solution （NBS） to maximize the utility of the system. Meanwhile, in the proposed algorithm, the demand of the maximal power, the maximal and the minimal transmission rate for each user are satisfied, and the fairness of resource allocation between users is ensured Simulation results show that compared with the Max-Rate algorithm, the proposed algorithm improves the fairness between users evidently, though the system throughput is slightly degraded, Therefore, the tradeoff between system throughput and user fairness is acquired by using the proposed algorithm.
