In this paper, we study the problem of cooperative spectrum sharing among a primary user
(PU) and multiple secondary users (SUs) under quality of service (QoS) constraints. The …

In this paper, we propose a limited feedback based underlay spectrum sharing scheme in a
Poisson cognitive network. Both primary and secondary transmitters are Poisson distributed …

Opportunistic Spectrum Sharing (OSS) is a promising solution for efficient spectrum
utilisation. In this paper, we analytically model an unreliable OSS system and investigate the …

In this paper, we propose an anti-interference cooperative spectrum sharing strategy in
cognitive two-phase full-duplex relaying networks, in which the secondary system acts as a …

In this paper, we propose a limited feedback based underlay spectrum sharing scheme
where a secondary decode-and-forward opportunistic relay network shares the spectrum …

We analytically model an unreliable opportunistic spectrum sharing (OSS) system through a
queueing theoretic framework. Both initiating secondary users and ongoing secondary users …

The focus of this paper is on the modeling and performance analysis of an unreliable
opportunistic spectrum sharing (OSS) system at the call level with sensitive secondary users …

In this paper, the quantity of interference on the primary user (PU) caused by the secondary
user (SU) is investigated. An underlay spectrum sharing network is considered, where the …

In this paper, the time allocation for multihop relay cognitive network is studied. For a N-hop
relay cognitive radio network, the achievable ergodic capacity with a given sensing time is …

With the rapid growth of wireless applications and services in recent decades, huge
demands of radio spectrum are created. Traditional approach of spectrum management …
