Visions of 4G
Barry G. Evans,K. Baughan +1 more
TL;DR: The initial work of the fourth generation (4G) Visions Group is outlined and a start to what will become an evolving vision of 4G for 2010 based around five elements: fully converged services, ubiquitous mobile access, diverse user devices, autonomous networks and software dependency.
Journal ArticleDOI
Cognitive spectrum utilization in Ka band multibeam satellite communications
Sina Maleki,Symeon Chatzinotas,Barry G. Evans,Konstantinos Liolis,Joel Grotz,Alessandro Vanelli-Coralli,Nicolas Chuberre +6 more
TL;DR: The potential of applying cognitive radio techniques in satellite communications (SatCom) in order to increase the spectrum opportunities for future generations of satellite networks without interfering with the operation of incumbent services is investigated.
Journal ArticleDOI
Low earth orbit satellite systems for communications
TL;DR: This paper heralds the coming of the new era with a tutorial approach to the system design and trade-offs of LEO constellation system design, which discusses orbital configurations, network topologies and routeing considerations, multiple access schemes and link performance design.
Journal ArticleDOI
Use cases and scenarios of 5G integrated satellite-terrestrial networks for enhanced mobile broadband: The SaT5G approach
Konstantinos Liolis,Alexander Geurtz,Ray Sperber,Detlef Schulz,Simon Watts,Georgia Poziopoulou,Barry G. Evans,Ning Wang,Oriol Vidal,Boris Tiomela Jou,Michael Fitch,Salva Diaz Sendra,Pouria Sayyad Khodashenas,Nicolas Chuberre +13 more
TL;DR: The selected use cases and scenarios for satellite communications positioning in the 5G usage scenario of enhanced mobile broadband in the SaT5G project are outlined.
Journal ArticleDOI
Robust time-domain timing and frequency synchronization for OFDM systems
TL;DR: A robust and efficient technique for frame/symbol timing and carrier frequency synchronization in OFDM systems is presented which uses a preamble consisting of only one training symbol with two identical parts to achieve reliable timing and frequency accuracy in the time-domain.
