This paper investigates subcarrier and power allocation in multiuser OFDM. The aim is to maximize the overall rate while achieving proportional fairness amongst users under a total power constraint. Achieving the optimal solution is computationally demanding thereby necessitating the use of suboptimal techniques. Existing sub-optimal techniques either use(More)
In an Orthogonal Frequency Division Multiplexing (OFDM) downlink scenario, we propose joint subcarrier and power allocation for Channel-Aware Queue-Aware scheduling while allowing multiple users to share a single OFDM symbol. Our approach is to combine subcarrier and power allocation by optimizing a user’s power allocation immediately after the user has(More)
