In this paper, a hop-by-hop relay selection strategy for multi-hop underlay cognitive relay
networks (CRNs) is proposed. In each stage, relays that successfully decode the message …

In this letter, we study the outage performance of cognitive relay networks with multiple
primary users in imperfect channel state information environment. Specifically, an exact …

This paper provides a general outage analysis framework for cooperative cognitive networks
with proactive relay selection over non-identical Rayleigh fading channels and under both …

Cooperative relaying combined with selection exploits spatial diversity to significantly
improve the performance of interference-constrained secondary users in an underlay …

In a cognitive relay network, a secondary cooperative transmission, sharing the same
spectrum band with primary transmissions, is considered. Assuming imperfect channel state …

Cooperative relaying combined with selection exploits spatial diversity to improve the
performance of interference-constrained secondary users in an underlay cognitive radio …

This paper investigates the impact of primary-user interference on the performance of a
cognitive relaying network consisting of a source, an amplify-and-forward relay and multiple …

In this paper, we present performance analysis for underlay cognitive decode-and-forward
relay networks with the Nth best relay selection scheme over Nakagami-m fading channels …

This paper investigates decode-and-forward (DF) buffer-aided relay selection for underlay
cognitive relay networks (CRNs) in the presence of both primary transmitter and receiver …

The outage behavior of a dual-hop multi-source multi-relay cooperative underlay cognitive
radio network is investigated in the presence of multiple primary transmitters and multiple …
