摘要：
MIMO-OFDMA is a promising technique for future broadband wireless communication systems.In this paper,the problem of allocating subcarriers among different users to maximize the total capacity is addressed.The optimal solution can be obtained by Hungarian method is proved,using two utility matrices,i.e.the Frobenius-norm matrix and the determinant matrix.Simulation results show that the proposed algorithm can achieve higher capacity than the existing algorithms,and it is globally optimal and easy to be implemented.
