Abstract :
Wireless spectrum environment cognitive is significant for improving spectrum efficiency, and cooperative diversity can enhance capacity of system and quality of service. A kind of cooperative diversity spectrum cognitive scheme based on game theory is proposed, which utilizing cooperate cognitive for data merging, along with exciting mechanism to spur selfish nodes in networks to be willing to provide cooperation. Simulations show that the performance of the cognitive radio networks is optimized.
