Abstract :
A novel algorithm is proposed for CDMA cognitive radio (CR) system which introduces Nash game into distributed power control. We design an effective cost function, of which there exists the Nash equilibrium. The existence and uniqueness of the Nash equilibrium have been proved. Simulation shows that this new algorithm converges faster comparing to the other two classic algorithms while the signal to interference ratio (SIR) meets the requirement.
