A Novel Non-cooperative Power Control Game Algorithm for Cognitive Radio
AO Xian-dan · Telecommunication Engineering · 2008
When cognitive radio (CR) network coexists with primary network by underlay, in order to guarantee primary users avoiding interference and also ensure cognitive radio sharing spectrum fairly, it is necessary for cognitive radio to perform power control. In this paper,an original pricing function with path gain is designed and a novel non-cooperative power control game algorithm via game theoretic is proposed. Simulation shows that the novel algorithm improves the pareto efficiency and enhances the system throughput,and also realizes resource allocation equality in cognitive radio network.
