- W2138402227 abstract "This chapter presents the solution of weighted ergodic sum-rate maximization subject to per user power and rate constraints in the uplink of orthogonal frequency division multiple access (OFDMA) systems within a single cell for discrete rates case. Conversely to the continuous rates scenario, the problem investigated consists of a limited achievable number of discrete rates. Numerical results showed that results became closer to the optimal continuous rates case when the target bit error rate increased or when the number of discrete rates increased. Furthermore, results showed that varying the weights allow providing more fairness in the system by increasing the priority of unfavored users, and that the maximum sum-rate is achieved when the weights are equal. Controlled Vocabulary Terms frequency division multiaccess; optimisation" @default.
