Physical layer security (PHY-security) takes the advantages of channel randomness nature
of transmission media to achieve communication confidentiality and authentication. Wiretap …

Full-duplex (FD) communication is a potential game changer for future wireless networks. It
allows for simultaneous transmit and receive operations over the same frequency band, a …

What is index modulation (IM)? This is an interesting question that we have started to hear
more and more frequently over the past few years. The aim of this paper is to answer this …

The full duplex (FD) technique, which allows the communication node to transmit and
receive signals over the same frequency band simultaneously, has the potential to double …

Device-to-device (D2D) communications are usually considered to be two user equipment
units (UEs) communicating directly without going through the central base station (BS). In …

A two-way relay non-orthogonal multiple access (TWR-NOMA) system is investigated, where
two groups of NOMA users exchange messages with the aid of one half-duplex decode-and …

In this paper, we explore the use of full-duplex radio to improve the spectrum efficiency in a
two-way relay channel where two sources exchange information through an multi-antenna …

In this paper, we propose a relay selection amplify-and-forward (RS-AF) protocol in general
bidirectional relay networks with two sources and N relays. In the proposed scheme, the two …

In this paper, we investigate the performance of multi-pair two-way relaying, in which
multiple pairs of users exchange information within pair, with the help of a shared relay …

Hardware impairments in physical transceivers are known to have a deleterious effect on
communication systems; however, very few contributions have investigated their impact on …
