This paper evaluates outage probability (OP) of a cooperative underlay cognitive radio
network in the presence of a passive secondary eavesdropper under joint impacts of limited …

In this paper, we investigate joint impacts of hardware impairments, imperfect channel state
information (CSI) and interference constraints at secondary users in an underlay decode …

This paper presents exact analysis of interference probability and outage probability of
underlay cooperative cognitive networks under quite general conditions such as imperfect …

Our contribution in this paper is the derivation of an exact closed-form outage probability
formula for underlay cognitive cooperative networks operated over Rayleigh fading …

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

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 …

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

In a spectrum sharing underlay context, we investigate the exact derivation of the outage
probability for relay-aided cognitive radio communications. To give more degrees of freedom …

The nature of cognitive radio is based on the co-existence of secondary users in the area of
primary users. Co-channel interference (CCI), therefore, is a vulnerable phenomenon in …

This work investigates two important performance metrics of underlay cooperative cognitive
radio (CR) networks: Interference cumulative distribution function of licensed users and …
