In view of the scarcity of spectrum resources in wireless communication, it is studied in this
paper over the two-hop cognitive secrecy transmission scheme of decoding and forwarding …

In this paper, we investigate the secrecy outage performance of the decode-and-forward
cognitive relay network with the existence of the co-channel interference, where all nodes …

This work investigates the secrecy outage performance of decode-and-forward (DF) buffer-
aided underlay cognitive relay networks (CRNs) with outdated channel state information …

In this paper, we investigate the secrecy outage performance of decode-and-forward (DF)
buffer-aided multi-antenna underlay cognitive relay networks (CRNs) in the presence of an …

In this paper, we started from the normal cellular communication system and studied a two-
hop multi-relay DF cognitive relay network system. Under the interference from the primary …

A common combing technique that Maximum Ratio Combing (MRC) in decode-and-forward
(DF) cognitive relay network has been studied in this paper. The direct links are available …

Spectrum sharing environment creates cross-interference between licensed network and
unlicensed network. Most existing works consider unlicensed interference (ie, interference …
