    We assess how virtualization and softwarization technologies can deliver part of the satellite gateway functionalities as virtual network functions and achieve a flexible and programmable control and management of satellite infrastructure. Under the Network Function Virtualization paradigm, building virtual network function blocks that compose a satellite gateway have been identified, and their interaction exhibited. This paper also gives insights on how the Satellite Cloud Radio Access Network approach can allow operators to provide software-defined networking-based: (1) bandwidth on demand, (2) dynamic QoS, and (3) satellite gateway diversity.

    This paper investigates the issue of low Earth orbit mobile satellite system frequency availability, which is depended upon a couple of novel discrete cosine transform and Walsh–Hadamard transform-based wideband spectrum compressed sensing methods. Both individual sensing and cooperative sensing scenarios are considered. For multiple satellites cooperatively sensing scenario, a joint fusion rule of OR and MAJ compromises probabilities of detection and false alarm is proposed. We assess the performance of the proposed schemes in terms of reconstruction precision, detection probability, and processing time with in-depth numerical simulations.

    HTTP/2 is a new IETF protocol that promises to reduce web page download latency and improve web browsing responsiveness with respect to HTTP/1.1. This paper discusses the main features of HTTP/2 and related set of TCP updates. The performance benefits of HTTP/2 are demonstrated by tests over an operational satellite access network, and potential issues are uncovered. The final discussion suggests how the specifications can evolve to enhance HTTP/2 performance and tune the protocol for long delay paths.

    This survey aims to review recent advances in the field of random access (RA) for satellite networks. Until recently, the use of RA in satellite networks was limited to initial logon or to low-efficiency messaging systems. The large satellite propagation delay and its noise-limited nature have recently triggered the development of some unconventional solutions to make RA protocols able to efficiently cope with collisions, which may find also application in terrestrial networks for machine-to-machine communications.

  5. Tri-orthogonal polarization diversity reception for non-geosynchronous satellite orbit ionospheric channels

    Diversity is known to offer advantages for communication links. We present simulations of satellite systems using real-time ionospheric and orbital data to illustrate the benefit of tri-orthogonal polarization diversity at the ground receiver. Through no alteration to the satellite, the approach suggests that increased diversity gain is offered for all systems considered over standard reception techniques.
