In this paper, a distributed interference suppression scheme is proposed for multi-cell uplink orthogonal frequency division multiple access (OFDMA) system. Firstly, we model resource allocation process as a non-cooperative game. Then we show the concept of Nash equilibrium (NE) and investigate its existence and uniqueness in detail. To enhance the performance of multi-cell OFDMA system, the further...
In this paper, we investigate the power and subcarrier allocation issue in the case of partial side information for downlink orthogonal frequency division multiple access (OFDMA) system. Relaxation method is utilized to characterize the necessary conditions of the optimal solution and the uniqueness of the optimal solution is proved. The game theoretical concept, surplus function is also introduced...
This article investigates two fairness criteria with regard to adaptive resource allocation for uplink orthogonal frequency division multiple access (OFDMA) systems. Nash bargaining solution (NBS) fairness and proportional fairness (PF) are two suitable candidates for fairness consideration, and both can provide attractive trade-offs between total throughput and each user's capacity. Utilizing Karush-Kuhn-...
