Recent literature has suggested the benefits of integrating licensed radio and cognitive radio
into a hybrid cooperative communication system. The fundamental properties of such hybrid …

Regulators around the world are currently setting rules and requirements that will allow for
mass-market access to TV White Spaces. It is expected that the opening of those frequency …

Cognitive radio is an emerging technology proposing the concept of dynamic spec-trum
access as a solution to the looming problem of spectrum scarcity caused by the growth in …

Motivated by the deployment of cognitive radio (CR) based relays in cellular networks, this
paper studies the fundamental limits of heterogeneous cognitive Gaussian relay channels …

In this paper, we have proposed the combination of a centralized & decentralized database
and distributed spectrum sensing method for secondary spectrum access. The potential …

Hybrid cognitive radio (CR) networks can jointly utilize both licensed and unlicensed radio
resources to gain better performance over pure licensed/unlicensed networks. This paper …

While regulators are opening up new spectrum by allowing special access to unused TV
channels in VHF/UHF bands, they are concentrating on means for protecting incumbents …

In this paper, we investigate the downlink spectral efficiency of infrastructure relay-enhanced
cellular systems. In particular, we use the average achieved spectral efficiency at an …

Multi-user settings present new challenges to the problems of characterizing the
fundamental limits and design of explicit schemes for a network. In the first direction of the …
