Abstract

Every BS wants to maxmize its sum downlink rate when minimizing co-channel interference with other cells. We have proved the game was an exact potential game (EPG) and found potential function. We use distributed iterative waterfilling power allocation (DIWPA) algorithm to find Nash equilibrium (NE) of EPG. Simulation result indicates DIWPA can achieve more dowmlink rate in evidence compared to the way which is called average power allcation (APA) algorithm.
