Spectrum sharing in multiple-antenna channels: A distributed cooperative game theoretic approach
ACT We consider a cognitive radio scenario in which two (or more) operators providing services in the same area wish to share the same licensed band of spectrum. This scenario diff...

Bayesian inference in linear models with a random Gaussian matrix : Algorithms and complexity
—We consider the Bayesian inference of a random Gaussian vector in a linear model with a random Gaussian matrix. We review two approaches to finding the MAP estimator for this m...

Channel state information based LLR clipping in list MIMO detection
—Suboptimal detection schemes, such as list MIMO detection, often face the challenge of having to “guess” at the decision reliability for some of the detected bits. A simple ...

Cooperative handoff in wireless networks
—In 802.11-based wireless networks the stations (STAs) are associated with the available access points (APs) and communicate through them. In traditional handoff schemes the STAs...
