Fifth generation (5G) mobile communication systems have entered the stage of commercial
deployment, providing users with new services, improved user experiences as well as a host …

We investigate physical-layer security for a multiuser underlay cognitive system with
hardware impairments (HIs) and channel estimation errors (CEEs), which comprises …

Physical layer security (PLS) with radio frequency (RF) energy harvesting (EH) in wireless
sensor networks has received significant interest as a technology for secure information …

This article investigates physical-layer security (PLS) for an energy-harvesting cognitive
network with nonorthogonal multiple access (EHCN-NOMA), where a cognitive base station …

A new class of iterated linearization-based nonlinear filters, dubbed dynamically iterated
filters, is presented. Contrary to regular iterated filters such as the iterated extended Kalman …

The paper proposes a novel artificial noise (AN) injection strategy in multiple-input single-
output multiple-antenna-eavesdropper (MISOME) systems under imperfect channel …

This paper considers a typical system composed of multiple energy-constraint users, a
destination, and a passive eavesdropper who may intercept confidential information. Each …

Interleave division multiple access (IDMA), which is based on interleaving sequences, may
be regarded as code domain non orthogonal multiple access (NOMA) and may confront …

This paper considers a full‐duplex (FD) secure transmission scheme with aid of the artificial
noise deployed at both transmitter and receiver under imperfect self‐interference …

Proper relay selection (RS) plays a key role for improving the reliability of wireless networks,
especially in the presence of jamming attacks and/or interferers. In this work, we consider …
