We consider a cognitive radio network consisting of M primary users, M primary receivers, a
secondary user with K channels and K secondary receivers. A channel is assigned to each …

Cognitive radio (CR) has been considered as a promising technology to enhance spectrum
efficiency via opportunistic transmission at link level. Basic CR features allow secondary …

This manuscript addresses the problem of Opportunistic Spectrum Access (OSA) in
Cognitive Radio Networks (CRNs). In the context of CRN, two types of users may coexist …

Opportunistic spectrum access in a cognitive radio network has been a challenge due to the
dynamic nature of spectrum availability and possible collisions between the primary user …

Given a set of communication links in cognitive radio networks, assume that the underlying
channel state information along each link is unknown; however, we can estimate it by …

We develop channel-aware opportunistic spectrum access strategies for cognitive radio
networks consisting of multiple secondary users. In addition to balancing between the cost of …

We consider an underlay cognitive radio (CR) communication system in which a cognitive
secondary user (SU) can access multiple primary spectrum channels only when its …

Opportunistic spectrum access (OSA) problem in cognitive radio (CR) networks allows a
secondary (unlicensed) user (SU) to access a vacant channel allocated to a primary …

In this paper, we investigate cost-aware joint learning and optimization for multi-channel
opportunistic spectrum access in a cognitive radio system. We investigate a discrete-time …

This manuscript addresses the problem of the Opportunistic Spectrum Access (OSA) in
Cognitive Radio Networks (CRNs). In a CRN, the main aim of a secondary user (SU), ie an …
