This study first modifies the traditional partial relay selection in cooperative cognitive
networks to prevent error propagation and then proposes exact and asymptotic outage …

This paper proposes an exact and limit analysis framework for numerically assessing the
outage performance of the maximum ratio combining in cooperative cognitive networks with …

Influence of channel information imperfection on outage probability of cooperative cognitive
networks with partial relay selection over independent and non-identical Rayleigh fading …

This paper investigates the effect of imperfect channel information on the outage
performance of underlay cooperative cognitive networks with reactive relay selection under …

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

Relay selection is an effective way to achieve considerable performance gains in cognitive
relay networks (CRN). In practice, the best relay may not always be selected, thus the study …

In this study, the author investigates the outage performance of cognitive relay networks, in
which the best relay is selected based on full and partial channel state information …

Proactive relay selection in cognitive radio networks has recently received considerable
attention. However, its outage probability analysis is limited to partially-identical fading …

In this paper, we consider amplify-and-forward cognitive relay networks in a spectrum-
sharing environment. We present the performance analysis under two different partial relay …

The performance of the best relay selection on the decode-and-forward (DF) mode cognitive
radio relay networks is studied. Some important factors, such as the outage probability, the …
