SPRINGERBRIEFS IN ELECTRICAL AND COMPUTER ENGIN...

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.
