Abstract :
This paper focuses on uplink transmission of OFDMA system in smart grid with heterogeneous traffic. The subcarrier and power allocation problem is formulated to maximize the throughput while maintaining the delay-constrained (DC) user rate and ensuring the NDC users fairness ratios. Considering these constraints, we propose two reasonable algorithms. The first is based on dual decomposition (DD) scheme, and shows near optimal performance in sum rate. And next, a low-complexity algorithm with reasonable simplicity is developed, displaying good performance in outrage probability for DC users. In the results, we also give the comparison with other algorithms.
