Abstract
In Cognitive Radio( CR) networks,under the premise of cognitive users satisfying the target SINR,in order to reduce each user’ s transmit power,non-cooperative game can be used. This paper studies joint control of power and rate for CR in the underlay type. It assumes the problem between Secondary Users( SUs) as a Non-cooperative Game (NG),and one joint control of power and rate alogorithm which is based on Delay Cost(DC) of SUs is proposed. It subjects to the tolerable interference limits,and proves the existence and uniqueness of the proposed alogorithm’ s Nash Equilibrium( NE) . Simulation results show that the alogorithm can attain higher utility and lower transmission delay using lower power,and sum interference made by the SUs can not exceed interference threshold.关键词
