摘      要：In this paper,we consider throughput maximization in cognitive radio systems with proper power *** particular,we incorporate location-awareness into the power control design and maximize the average throughput of the cognitive *** we shall show,the proposed approach effectively utilizes the“spatial opportunityto maximize the system throughput,which clearly outperforms traditional power control ***,the proposed approach still exhibits significant throughput gain even considering imperfect position information,with appropriate robust design modifications.
