In this paper, the performance of a dual-hop multiuser underlay cognitive network is
thoroughly investigated by using a decode-and-forward (DF) protocol at the relay node and …

In this paper, the impact of co-channel interference (CCI) on the performance of an underlay
cognitive radio network over Nakagami-m fading channels is thoroughly presented and …

In this paper, we analyze the packet transmission time in a cognitive cooperative radio
network (CCRN) where a secondary transmitter (SU-Tx) sends packets to a secondary …

In this letter, we propose a power allocation scheme for statistical quality-of-service (QoS)
provisioning in multi-relay decode-and-forward (DF) cognitive networks (CN). By …

Cognitive radio allows secondary users to use the same existing frequency spectrum band
as primary users. This co-existence has several impacts on the whole network. This has …

In this letter, we consider a cognitive radio network with imperfect channel state information
where secondary users transmit signals using multi-hop relaying. When the channels …

Consider a multi‐user underlay cognitive network where multiple cognitive users
concurrently share the spectrum with a primary network with multiple users. The channel …

Our contribution in this paper is the derivation of an exact closed-form outage probability
formula for underlay cognitive cooperative networks operated over Rayleigh fading …

This paper studies the outage performance behaviour of underlay cooperative cognitive
networks over Nakagami‐m fading channels. For time savings in collecting simulation …

This paper proposes exact and limit outage probability expressions for thoroughly
evaluating the performance of cooperative cognitive networks with opportunistic relay …
