Physical layer security (PLS) has emerged as a new concept and powerful alternative that
can complement and may even replace encryption-based approaches, which entail many …

Physical layer security (PLS) has been extensively explored as an alternative to
conventional cryptographic schemes for securing wireless links. Many studies have shown …

To support various new use cases from vertical industries besides enhanced mobile
broadband communication services, the 5G system aims to provide higher speed, lower …

The 5G wireless cellular networks are evolving, to meet the drastic subscriber demands in
near future. This is accompanied with a rise in the energy consumption in cellular networks …

In this paper, we develop various beamforming techniques for downlink transmission for
multiple-input single-output nonorthogonal multiple access (NOMA) systems. First, a …

In recent times, security and privacy at the physical (PHY) layer has been a major issue of
several communication technologies which comprise the internet of things (IoT) and mostly …

Through direct communication, device-to-device (D2D) technology can increase the overall
throughput, enhance the coverage, and reduce the power consumption of cellular …

In this paper, we consider physical-layer security for device-to-device (D2D)
communications underlaying cellular networks in which cellular users are under threat from …
