This paper investigates the physical layer security problem of cognitive decode-and-forward
relay networks over Nakagami-m fading channels. We consider the relaying communication …

In this paper, the secrecy outage performance of an underlay cognitive decode-and-forward
relay network over independent but not necessarily identical distributed Nakagami-m fading …

In this letter, we analyze the physical layer secrecy performance of a two-hop cooperative
cognitive underlay relay network with a decode and forward relay and a passive …

In this letter, we consider an underlay cognitive radio network in which a secondary
transmitter (ST) communicates with a secondary destination (SD) with the aid of multiple …

This paper investigates the secrecy performance of an underlay cooperative cognitive
relaying network, wherein a secondary source vehicle communicates with a fixed secondary …

In this paper, we introduce transmit antenna selection/maximal-ratio combining (TAS/MRC)
scheme in dual-hop randomize-and-forward (RaF) cognitive multiple-input multiple-output …

This letter proposes several relay selection policies for secure communication in cognitive
decode-and-forward relay networks, where a pair of cognitive relays is opportunistically …

In this paper, we analyze the secrecy performance of the decode-and-forward (DF) relay
system in generalized-K fading channels. In a typical four-node communications model, a …

The authors investigate the secrecy performance of a cooperative relaying network, wherein
a fixed source communicates with a fixed destination via an amplify‐and‐forward mobile …

In this, we propose a generalized partial relay selection (PRS) protocol to enhance the
secrecy performance for cooperative cognitive radio networks (CRNs) in terms of the …
