A cognitive radio network (CRN) is formed by either allowing the secondary users (SUs) in a
secondary communication network (SCN) to opportunistically operate in the frequency …

This paper studies optimal bandwidth and power allocation in a cognitive radio network
where multiple secondary users (SUs) share the licensed spectrum of a primary user (PU) …

In this paper, we consider a cognitive radio (CR) network where a secondary (cognitive)
user shares the spectrum for transmission with a primary (non-cognitive) user over block …

In this paper, a new spectrum-sharing model called sensing-based spectrum sharing is
proposed for cognitive radio networks. This model consists of two phases: In the first phase …

This paper considers spectrum sharing for wireless communication between a cognitive
radio (CR) link and a primary radio (PR) link. It is assumed that the CR protects the PR …

In this paper, we analyze the capacity gains of opportunistic spectrum-sharing channels in
fading environments with imperfect channel information. In particular, we consider that a …

This paper is concerned with spectrum sharing for wireless communication, where a
secondary or cognitive radio (CR) link communicates over the same bandwidth that has …

In cognitive radio (CR) networks, there are scenarios where the secondary (lower priority)
users intend to communicate with each other by opportunistically utilizing the transmit …

Cognitive radio (CR) has been considered as a promising technology to improve the
spectrum utilization. In this paper we analyze the capacity of a CR network with average …

This paper studies the information-theoretic limits of a secondary or cognitive radio (CR)
network under spectrum sharing with an existing primary radio network. In particular, the …
