This letter considers amplify-and-forward (AF) cognitive relay networks with interference
power constraint and transmit power constraint in a spectrum-sharing context. In particular …

In this letter, with the primary user's (PU's) interference, we investigate the performance of
the secondary user (SU) in spectrum sharing cognitive relay networks. Considering the …

In this letter, considering a cognitive relay network with the maximum transmit power limit in
a spectrum sharing scenario, the exact outage probability of secondary system is derived …

This paper investigates the performance of an underlay cognitive relay system where
secondary users (SUs) suffer from a primary outage probability constraint and spectrum …

The outage performance is investigated for a cognitive relay system with underlay spectrum
sharing model. It is shown that the dependence among the received SNRs is introduced due …
