摘要：This paper studied the performance gain of Amplify-and-Forward (AF) cooperation technology in asymmetry Cognitive Radio (CR) interference communication systems. The main contributions are the derivation of the closed-form math expressions of outage and the throughput for Licensed and Cognitive Users in cognitive cooperative communication systems under flat Rayleigh fading channel. Under the condition of transparent from Cognitive User (CU) to Licensed User (LU) and random LU package arrivals, the paper analyzed the power allocation algorithm and the throughput for the CU and derived the Adaptive Power Allocation (APA) algorithm for cognitive cooperative communication systems. Simulation verified the theory analyses and the numerical results show that the cooperation technology improves the overall system performance for both Licensed and Cognitive Users. © 2011 IEEE.
