Abstract
In this paper, we formulate a proportional fairness problem for downlink OFDM systems. Different from all the previous works, a completely new framework is presented by decomposing it into two levels: the master problem and the subproblems. Our proposed algorithm could remarkably reduce the computational complexity in the base station and the feedback overhead. Numerical results demonstrate that this algorithm could provide much better proportional fairness as well as enhance the system throughput.
