Information Theoretic Perspective on Cognitive Radio Networks "Prof. A. K. Chaturvedi, IIT Kanpur."

Cognitive radios hold tremendous promise to increase the spectral efficiency of wireless systems. We will start with a brief introduction to information theory and cognitive radio networks and then discuss the fundamental capacity limits in such networks. We will characterize a cognitive radio as an intelligent device that can use side information about its environment to improve spectral utilization.
