Along with the ongoing evolution of multiple antenna communication systems, new physical
layer security techniques are continuing to achieve higher levels of secrecy. Most physical …

Purpose Multiple input multiple-output (MIMO) has emerged as one among the many
noteworthy technologies in recent wireless applications because of its powerful ability to …

This paper proposes a novel joint resource allocation algorithm combining dynamic user
grouping, multi-cell cooperation, and resource block (RB) allocation for single carrier …

In this paper, a two-hop decode-and-forward wireless powered relaying cognitive radio
network with interference alignment over Rayleigh fading channels is investigated. The …

In this paper, a two-hop decode-and-forward cognitive radio system with deployed
interference alignment is considered. The relay node is energy-constrained and scavenges …

In this paper, a cooperative multi-hop vehicle-to-vehicle communication over free-space
optics (FSO) medium is examined, where unmanned aerial vehicles act as relay nodes …

The broadcast nature of wireless networks makes them vulnerable to eavesdropping
attacks; therefore, physical layer security (PLS) becomes essential to protect the signal at the …

This paper presents a generalized closed-form beamforming technique that can achieve the
maximum degrees of freedom in compounded multiple-input multiple-output (MIMO) …

In this paper, we first exploit the inter-user interference and inter-cell interference as useful
references to develop a robust transceiver design based on interference alignment for a …

Interference alignment (IA) is an innovative wireless transmission strategy that has shown to
be a promising technique for achieving optimal capacity scaling of a multiuser interference …
