On Full-Duplex Communication in Cooperative Cognitive Radio Networks

Abstract

Taking a full-duplex (FD) technique into account, a design of cooperative cognitive radio networks (CCRN) is addressed. The FD communication in the CCRN is enabled by employing simultaneous transmitting and receiving antennas for the secondary users. From the preliminary results via numerical evaluation, it is expected that the proposed FD multiple-input-multiple-output CCRN framework can provide a performance gain over the conventional CCRN frameworks.
