We investigate the secrecy performance of cellular multiuser two‐way relay networks, where
the bidirectional information exchange between a multiantenna base station (BS), and …

In this paper, we investigate the performance of secure cellular multiuser two-way amplify-
and-forward relay networks, wherein one N a-antenna base station (BS) exchanges …

We present two physical layer secure transmission schemes for multiuser multirelay
networks, where the communication from M users to the base station is assisted by direct …

In this paper, we study a downlink multiuser network in which one base station sends its
message to one of multiple users, assisted by one of multiple intermediate decode-and …

This paper proposes relay selection to increase the physical layer security in multiuser
cooperative relay networks with multiple amplify-and-forward relays, in the presence of …

In this paper, we investigate the secrecy outage performance of a full-duplex cellular
multiuser two-way amplify-and-forward relay network, where a multiantenna base station …

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 paper, we study the information-theoretical security of a downlink multiuser
cooperative relaying network with multiple intermediate amplify-and-forward (AF) relays …

We study a relay and user selection scheme to improve the secrecy performance of
cooperative multi-user multiple amplify-and-forward (AF) relay network. Nevertheless, relay …

This paper studies physical layer security for two-way relay non-orthogonal multiple access
systems. Specifically, by employing a decode-and-forward relay and considering both the …
