Full-duplex communication in cooperative cognitive radio networks: Preliminary results

We address the design of cooperative cognitive radio networks (CCRN) adopting a full-duplex (FD) technique. In order to enable FD communication in the CCRN, simultaneous transmitting and receiving antennas are employed for the secondary users. Some preliminary results from numerical evaluation indicate that the proposed FD multiple-input-multiple-output CCRN framework can provide a considerable performance gain over the conventional CCRN frameworks.
