Decentralized Cross-Tier Interference Mitigation in Cognitive Femtocell Networks
—In this paper, recent results in game theory and stochastic approximation are brought together to mitigate the problem of femto-to-macrocell cross-tier interference. The main re...

Optimal Power Allocation for Cognitive Radio Under Primary User's Outage Loss Constraint
In this paper, we consider a secondary link sharing the spectrum with a primary link in a fading cognitive radio (CR) network. Instead of applying the conventional interference pow...

Distributed Power Control for Cognitive User Access based on Primary Link Control Feedback
—We venture beyond the “listen-before-talk” strategy that is common in many traditional cognitive radio access schemes. We exploit the bi-directional nature of most primary c...

Sensing and Communication Tradeoff for Cognitive Access of Continues-Time Markov Channels
—Dynamic spectrum access (DSA) aims to improve spectrum efficiency via spectrum sensing and optimal spectrum access. An essential component in DSA is the joint design of sensing...
