This paper deals with the crucial issue of random access (RA) preamble design and
detection for fifth generation new radio (5G NR) enabled satellite communication systems. 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 …

The computational complexity of FFT (Fast Fourier Transform) processing in an OFDM
(Orthogonal Frequency Division Multiplex) based receiver is large with a large amount of …

Satellite communication is expected to play a pivotal role in supporting the ubiquitous
machine-to-machine (M2M) connection. Due to its wide beam coverage, however, one of the …

Next generation satellite payload technology is expected to provide digital processing
capabilities. This will pave the way to regard satellites as flying base stations. However, the …

Satellite-based non-terrestrial networks (NTNs) can provide connectivity to geographical
regions with inadequate cellular coverage. The 3rd Generation Partnership Project is …

We consider the problem of uplink timing synchronization for Orthogonal Time Frequency
Space (OTFS) modulation based systems where information is embedded in the delay …

With the emerging of the massive Machine Type Communication usage scenario, the legacy
Random Access (RA) procedures need to be fully renewed to meet the huge number of …
