Abstract :
Interference management is a key problem to system performance in the next-generation wireless networks. In this paper, a distributed cooperation policy selection scheme for interference minimization is proposed to perform subcarrier assignment for uplink multi-cell OFDMA systems by adopting a new solution concept, the correlated equilibrium, which achieves better performance by allowing each user to consider the joint distribution of the users´ actions. The proposed algorithm exhibits low complexity and converges to a set of correlated equilibria with probability one. Simulation results demonstrate that the proposed algorithm offers a good performance.
