The satellite communications (SatCom) system is a representative technology for global
coverage and seamless communications in next-generation communication systems. This …

Abstract The Internet of Things (IoT) has drawn an enormous attention into the scientific
community thanks to unimaginable before applications newly available in everyday life. The …

Massive access, also known as massive connectivity or massive machine-type
communication (mMTC), is one of the main use cases of the fifth-generation (5G) and …

Research and processing development on satellite communications has strongly re-
emerged in recent years. Following the prosperity of various wireless services provided by …

This paper investigates the physical layer security of a satellite network, whose downlink
spectral resource is shared with a terrestrial cellular network. We propose to employ a multi …

In this article, we investigate the issue of massive access in a beyond fifth-generation (B5G)
multibeam low-Earth orbit (LEO) satellite Internet-of-Things (IoT) network in the presence of …

We propose a data-aided transmit beamforming scheme for the multi-user multiple-input-
single-output (MISO) downlink channel. While conventional beamforming schemes aim at …

This work focuses on the promising Rate-Splitting Multiple Access (RSMA) and its
beamforming design problem to achieve max-min fairness (MMF) among multiple co …

This paper investigates the downlink (DL) transmit design for massive multiple-input multiple-
output (MIMO) low-earth-orbit (LEO) satellite communication systems, where only the slow …

The present work focuses on the forward link of a broadband multibeam satellite system that
aggressively reuses the user link frequency resources. Two fundamental practical …
