A Non-Cooperative Game Theoretic Approach for Multi-Cell OFDM Power Allocation

In this paper, the authors develop a distributed adaptive power allocation based on game theory in the Orthogonal Frequency Division Multiplexing (OFDM) cellular systems. In this paper, power control problem is solved based on the idea of the Nash Equilibrium (NE) from non-cooperative game. In this regard, a utility function is proposed that each user seeks to select a transmit power level such that maximizes its own utility by adjusting the transmit power on each subchannel.
