In this survey paper, we review the random access (RA) techniques with particular emphasis
on the issues and the possible solutions applicable to satellite networks. RA dates back to …

With the increasing need for converged and ubiquitous broadband service support, next-
generation mobile radio technologies are posed to be more efficient in different aspects …

The field of satellite communications (SatCom) is enjoying renewed attention in the global
telecommunications market, and high-throughput satellites, with their multiple spot beams …

Oscillator phase noise limits the performance of high speed communication systems since it
results in time varying channels and rotation of the signal constellation from symbol to …

In this paper we present the concept of cognitive satellite terrestrial radios (CSTR) for hybrid
satellite-terrestrial systems (HSTS). The cognitive radio (CR) technology is being motivated …

Future communication subsystems of space exploration missions can potentially benefit
from software-defined radios (SDRs) controlled by machine learning algorithms. In this …

There is an urgent need for substantially enhancing random access schemes to be able to
support native massive machine-to-machine communications in the next generation …

Abstract We evaluate the performance of APSK modulation for wireless systems and
compare it with the performance of more conventional QAM systems. In previous literature …

In line-of-sight (LOS) radio channels maximum multiple input multiple output (MIMO)
channel capacity is obtained if an orthogonal MIMO channel transfer matrix is available. For …

Satellite communication is facing the urgent need of improving data rate and efficiency to
compete with the quality of service offered by terrestrial communication systems. An …
