Opportunistic Power Control for Multi-Carrier Interference Channels

摘要: We propose a new method for opportunistic power control in multi-carrier interference channels delay-tolerant data services. In doing so, we utilize game theoretic framework with novel constraints, where each user tries to maximize its utility distribute d and manner, while satisfying the game’s constraints by adapting transmit channel. this scheme, users more on good sub-channels do opposite bad sub-channels. way, addition allocated sub-channel, total of all also depends channel conditions. Since user’s level levels othe r users, belongs generalized Nash equilibrium (GNE) problems, which general, is hard analyze. show that proposed has GNE, derive sufficient conditions un iqueness. Besides, pricing scheme maximizing throughput an o pportunistic manner under constraint; provide al gorithm’s convergence GNE’s uniqueness. Simulations confirm our yields higher and/or significantly improved efficiency as compared other exist ing methods.
