Abstract
Focusing on the low throughput of fair subcarrier allocation in cooperative OFDMA system, an improved algorithm with single subcarrier capacity threshold and cooperative power factor is proposed. In this algorithm, the users with bad channel can not occupy too many subcarrier, and the power for cooperating with other users of users with good channel is limited. Simulation results show that this algorithm can increase the total channel capacity with less loss of fairness.
