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

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

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) …

We propose cognitive spectrum sharing with generalized selection combining (GSC) at the
secondary user (SU) in the presence of multiple primary transceivers with outdated channel …

This study investigates outage probability (OP) of a generalised decode‐and‐forward‐
based multiuser spectrum sharing relay system. In practice, the secondary users are …

In this paper, the performance of a multi-hop underlay cognitive radio network (UCRN) is
thoroughly assessed. The co-existence of a primary transceiver and co-channel interference …

In this paper, the problem of sub-channel selection for carrier aggregation (CA) systems is
examined. CA enables the achievement of high data rate links via simultaneous …

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

This work investigates the impact of outdated channel state information (CSI) on the outage
performance of decode-and-forward (DF) buffer-aided underlay cognitive relay networks …

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