Outage Performance of Cognitive Relay Networks with Interference from Primary User

Cognitive relay networks employ cooperative relaying scheme in the cognitive secondary user transmission. In this letter, we theoretically derive a closed form expression and a lower bound of the outage performance for underlay cognitive relay networks considering the interference from the primary t...
