Several works have studied relaying in cognitive radio networks in terms of outage
probability. The main challenge in such works is finding a mathematical expression for this …

In this article, the authors study the effect of peak interference power constraint given by the
primary receiver on the performance of multi‐hop cognitive amplify‐and‐forward (AF) relay …

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, the outage performance is investigated for cognitive dual-hop relay networks
with amplify-and-forward (AF) relay and selection combining (SC) receiver at the destination …

In this study, the authors investigate the outage probability of underlay cognitive radio
systems with relay selection. In particular, they consider a secondary multi‐relay network …

In this letter, we propose two relay selection schemes in cognitive relay networks. According
to the proposed schemes, the number of relays involved in the opportunistic relaying is …

This paper evaluates the outage probability of cognitive relay networks with cooperation
between secondary users based on the underlay approach, while adhering to the …

In this paper, we investigate the outage performance of a decode-and-forward (DF) underlay
cognitive two-way relay system with direct link using time division broadcast protocol in the …

In this paper, the outage performance of a cognitive radio network with a pair of secondary
transmitter and receiver is investigated in the presence multiple primary users over a …

In the current study of cognitive relay networks, most related works focus on the effect of
interference from secondary users (SUs) to primary receivers (PRs), while neglecting the …
