Cognitive radio combined with bidirectional relay could greatly improve spectrum utilization. In this paper, we consider a multi-relay cognitive radio network with imperfect channel state information (CSI). Interference to primary users and secondary users' quality of service (QoS) are the main factors considered and optimized. Using semidefinite relaxation (SDR), the optimization problem could be transferred into a convex form and solved. Simulation results validate the effectiveness of our proposed scheme compared to nonrobust one, particularly in ensuring the stability of the system. |
