摘要：To enhance the spectrum utilization efficiency, cognitive radio and full duplex techniques are considered as the two main effective emthods. For the two-way communication underlay full duplex cognitive radio networks, this paper studied the power control problem to enhance the secondary transmission while satisfy the primary transmission requirement. In practical scenarios, only the primary user (PU) statistical channel state information (CSI) is retrievable for the secondary users (SUs), and the joint power allocation between SUs are studied utilize the statistical CSI. Simulation results show that the proposed approach can provide an improved performance, as compared to the existing equal resource allocation (ERA) scheme.
