Non‐orthogonal multiple access (NOMA), an emerging technology to improve system
capacity and spectrum efficiency, has attracted significant attention. In this study, the authors …

Amplify-and-forward-based two-way relaying (TWR-AF) promises significant benefits in
wireless networks. In this paper, we aim to obtain unified expressions to determine the …

This paper focuses on the complexity issue of relay selection for fifth-generation (5G) large-
scale secure two-way amplify-and-forward (TWR-AF) relay systems with massive relays and …

We propose and analyze two multiple-input-multiple-output (MIMO) two-way relaying
schemes with an amplify-and-forward protocol in Nakagami-m fading channels, where multi …

Energy harvesting, which is an emerging technology to prolong the lifetime of energy‐
constrained wireless networks, has received significant attention. In this study, the authors …

We consider two end users which have asymmetric traffic requirements in terms of both data
rate and outage probability. They exchange information in Rayleigh flat-fading channels …

In this paper, we focus on the issue of energy efficiency (EE) optimization of amplify-and-
forward-based energy harvesting two-way relaying systems. Utilizing the statistical channel …

In this paper, we study the outage performance of an amplify-and-forward (AF)-based two-
way relaying (TWR) system with multiple relays where a single relay selection is performed …

For a diverse many-to-many-to-one (MMO) Internet of things (IoT) network, it is essential and
significant to ensure the access fairness of things with limited cost of performance, ie, each …

Both energy efficiency (EE) and spectral efficiency (SE) are two important design criteria that
can hardly be achieved simultaneously. In this paper, we investigate the EE-SE tradeoff for a …
