Abstract
The concept of cognitive networks has emerged as one of the efficient means for utilizing the scarce spectrum by allowing spectrum sharing between a licensed primary network and a secondary network. In this talk, we briefly present an overview of various recently proposed types of cognitive networks and then discuss some fundamental capacity results of these networks. The talk goes then over the potential offered by free space optical communications to relieve spectrum scarcity and then summarizes some of the challenges that need to be surpassed before such kind of systems can be massively deployed.
