英文摘要：

Under the constraint of total transmission power at the sender, this paper proposes a resource allocation algorithm for MIMO-MC-CDMA systems. In this algorithm, the system throughput is optimized by assigning the power, the sub-bands and the code channels among users, and the bandwidth fairness is implemented by limiting the maximum and minimum occupied code channels of all users. The throughput maximization problem is modelled as a constrained optimizaiton problem, which is solved by the Lagrange multiplier method. Simulated results show that, as compared with the existing algorithms, the proposed algorithm significantly increases the throughput and accelerates the convergence.
