In this paper we present two strategy to maximize user's throughput in Cooperative MU-OFDM network while considering fairness of users. Our strategy is proposed to improve throughput and fairness of users only with limited feedback. With perfect instantaneous channel state information(CSI) at receiver, the resource allocating strategy not only decided in base station, but also decided in users of...
The adaptive resource allocation will be a key technique of the OFDMA systems in the future wireless networks due to the great improvement of the network throughput. However, in order to allocate the subcarriers and power adaptively, the users need to send back the channel state information (CSI) periodically to the base station. The feedback overhead is huge, and it brings a big burden to the uplink...
The focus of this paper is the improvement of the average sum rate of an orthogonal frequency-division multiple-access (OFDMA) system in uplink by exploiting multiple users' tap correlation information. We propose two statistical opportunistic scheduling schemes that schedule users based on the average subcarrier gains. We characterize the optimality of these schemes and compare their simulation results...
