Low-Earth orbit (LEO) satellites can play an important role in providing seamless coverage
for the Internet of Things (IoT). In satellite-based IoT (SIoT) networks, IoT devices can …

The 5G ecosystem is radically shifting Information and Communication Technologies (ICT)
towards a system directly tailored and optimised to support vertical markets and services. In …

Low earth orbit (LEO) satellite communication based on 3GPP standard is seen as a
promising solution to rolling out communication services in areas without terrestrial base …

Integrated satellite-terrestrial communications networks aim to exploit both the satellite and
the ground mobile communications, thus providing genuine ubiquitous coverage. For 5G …

As a promising paradigm toward the sixth generation mobile communication, integrated
satellite-terrestrial networks (ISTNs) can greatly extend network coverage and reduce the …

Non-terrestrial networks (NTN) are expected to play a key role in extending and
complementing terrestrial 5G networks in order to provide services to air, sea, and un-served …

The integration of non-terrestrial networks into the 5G ecosystem is mainly driven by the
possibility of provisioning service in remote areas. In this context, the advent of flying base …

Satellite-ground integrated vehicular network can provision ubiquitous and unlimited
network connectivity for massive vehicles, and is expected to play a vital role in 6G …

In this paper, we discuss general data-framing and optimization, parallel frequency-phase
estimation, and powerful frequency estimator for satellite communications. Based on the …

In this paper, we propose a robust random access preamble detection scheme for 5G
integrated low-earth-orbit (LEO) satellite. By converting the traditional frequency domain …
