This letter presents the outage performance analysis for a cognitive relay network (CRN)
with imperfect channel knowledge estimations. Under the condition of imperfect channel …

In this letter, exact outage probability of decode-and-forward (DF) and incremental DF (IDF)
relaying are respectively derived over underlay cognitive relay networks. Particularly, we …

In this study, the authors investigate the effect of imperfect channel state information (CSI) on
underlay cognitive radio networks in the presence of multiple primary users (PUs) …

This paper analytically evaluates the outage performance of relaying cognitive networks with
reactive relay selection and selection combining under general operation conditions such as …

In the presence of the primary user's interference, the outage probability of a dual-hop
decode-and-forward (DF) cognitive relay network (CRN) over Rayleigh fading channels is …

Cognitive relay networks employ cooperative relaying scheme in the cognitive secondary
user transmission. In this letter, we theoretically derive a closed form expression and a lower …

underlay cooperative cognitive networks under quite general conditions such as imperfect …

This paper evaluates outage performance of reactive relay selection in cognitive radio
networks over Nakagami-m fading channels under consideration of imperfect channel …

For cognitive relay networks coexisting with multiple primary transceivers, we investigate the
secondary system performance using outdated channel state information (CSI). We propose …

Selective cooperation is a well investigated technique in non-cognitive networks for efficient
spectrum utilization and performance improvement. However, it is still a nascent topic for …
