Abstract

  Cognitive radio (CR) is one of the main technologies to solve the spectrum under-utilization problem in future generations of wireless systems. In this talk, we will introduce a game theoretic framework for cognitive radio (CR) wireless networks in which each user could adapt the parameters and operations according to the dynamic environment and its past experience to achieve optimal performance of itself as well as the equilibrium point of the whole network. By combining recent results in information theory, wireless network, control theory, and artificial intelligence, we establish a series of distributed learning algorithms for each user to improve its performance without causing adverse effects on others.
