A computationally efficient multi-criteria ranking based greedy (MCRG) algorithm is proposed for physical resource block (PRB) allocation in the fourth generation (4G) systems, where the users' utilities are ranked with multiple criteria, to enhance the performance of the basic greedy algorithm. The MCRG algorithm not only outperforms the previous single criterion ranking based greedy algorithm in...
In this paper, we consider the bit rate maximizing problem and power minimizing problem with integer bit allocation. We will derive the duality between these two problems. We will show that if a transceiver is optimal for the power-minimizing problem, it is also optimal for the rate maxi-mizing problem, and the converse is true. For the power minimization problem with integer bit allocation, the solution...
