Secure Cognitive Reactive Decode-and-Forward Relay Networks: With and Without Eavesdropper
In this paper, we study performances of cooperative relay networks in cognitive radio with reactive multiple decode-and-forward (DF) relays. In particular, we first derive exact and asymptotic expressions of o...
