Since 1990s, the investigations of aerospace communication segment have not only been
concerned with satellites, but increasingly with lower altitude repeaters flying in the …

Inter‐satellite link (ISL) will play an increasingly important role in the next generation of
global navigation satellite system (GNSS). The inter‐satellite distances in the GNSS vary …

The introduction of adaptive coding and modulation (ACM) in DVB-S2 improves system
capacity. Transmission mode is adapted to receiving conditions which are fed back through …

This paper investigates the ways of improving the Grade-of-Service (GoS) in a coexistence
scenario with different user types in a multiple High Altitude Platforms (HAPs) system with …

In a cooperative relay network, a relay (R) node may facilitate data transmission to the
destination (D) node when the latter node cannot correctly decode the source (S) node data …

Multiple-input multiple-output (MIMO) technology, which makes use of the spatial dimension
by utilising multiple antennas at the transmitter and receiver, has proved an efficient solution …

Given that single-state model can only describe single channel environment, while multiple-
state model brings more parameters and more complicated simulation work, a three-state …

Stratospheric communication systems operating in the millimetre frequency bands are
subject to atmospheric impairments caused by rain and scintillation. In this paper we …

High altitude platform (HAP) system offers establishment of communication links with
predominantly line-of-sight (LOS) conditions due to high elevation angles. However, in …
