Distributed beam-forming and power control in multi-relay underlay cognitive radio networks: A game-theoretical approach
Alireza Louni, Babak Khalaj · 2011
In this paper, we propose a power control algorithm incorporating distributed beam-forming via multi-relay structure with underlay cognitive radio architecture. This problem is modeled as a non-cooperative game and a novel distributed algorithm is designed to achieve Nash equilibrium (NE). At e
