This brief focuses on the use of full-duplex radio in cognitive radio
networks, presenting a novel spectrum sharing protocol that allows the
secondary users to simultaneously sense and access the vacant spectrum.
This protocol, called "Listen-and-talk" (LAT), is evaluated by both
mathematical analysis and computer simulations in comparison with other
existing protocols, including the listen-before-talk protocol. In
addition to LAT-based signal processing and resource allocation, the
brief discusses techniques such as spectrum sensing and dynamic spectrum
access. The brief proposes LAT as a suitable access scheme for cognitive
radio networks, which can support the quality-of-service requirements of
these high priority applications. Fundamental theories and key
techniques of cognitive radio networks are also covered.
Listen and Talk: Full-duplex Cognitive Radio Networks is designed for
researchers, developers, and professionals involved in cognitive radio
networks. Advanced-level students studying signal processing or
simulations will also find the content helpful since it moves beyond
traditional cognitive radio networks into future applications for the
technology.
