In traditional cognitive radio networks, Secondary Users (SUs) typically access the spectrum of Primary Users (PUs) by a two-stage "Listen-Before-Talk" (LBT) protocol, i.e., SUs sense the spectrum holes in the first stage before transmit in the second stage. In this paper, the authors propose a novel "Listen-And-Talk" (LAT) protocol with the help of the Full-Duplex (FD) technique that allows SUs to simultaneously sense and access the vacant spectrum. Analysis of sensing performance and SU's throughput are given for the proposed LAT protocol.
