Listen and Talk: Full-duplex Cognitive Radio Networks

This brief focuses on the use of full-duplex radio in cognitive radio networks, presenting a novel spectrum sharing prool that allows the secondary users to simultaneously sense and access the vacant spectrum. This prool, called “Listen-and-talk” (LAT), is evaluated by both mathematical analysis and computer simulations in comparison with other existing prools, including the listen-before-talk prool. In addition to LAT-based signal processing and resource allocation, the brief discusses tec...
