This paper investigates physical layer security (PLS) in cognitive radio inspired non-
orthogonal multiple access (CR-NOMA) networks with multiple primary and secondary …

Internet-of-Vehicle (IoV) enabled Maritime Transportation Systems (MTS) communication is
anticipated to support ultra-reliable and low latency, diverse quality-of-service (QoS) and …

This paper investigates the secrecy performance of a two-user downlink non-orthogonal
multiple access systems. Both single-input and single-output and multiple-input and single …

This paper considers the secrecy outage performance of a multiple-relay assisted non-
orthogonal multiple access (NOMA) network over Nakagami-m fading channels. Two time …

IRS is of low-cost and energy-efficiency and will be a promising technology for the future
wireless communications like sixth generation. To address the problem of conventional DM …

In this paper, we consider an underlay multiple-input-multiple-output (MIMO) cognitive radio
network (CRN) including a pair of primary nodes, a couple of secondary nodes, and an …

We analyze a secure dual-hop mixed radio frequency-free space optical (RF-FSO) downlink
simultaneous wireless information and power transfer system. The FSO link and all RF links …

In this work, we analyze the secrecy outage performance of a dual-hop relay system
composed of multiple-input-multiple-output radio-frequency (RF) links and a free-space …

This paper considers a secure nonorthogonal multiple access system, where confidential
messages are transmitted from a base station to multiple legitimate destinations and …

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 …
