      We propose a constant false alarm rate frame detector for satellite-based automatic identification system in the presence of additive white Gaussian noise and frequency offset. False alarm probability and detection probability of the proposed detector, which is based on the periodicity of the training sequence, are analyzed in this paper. Simulation results prove that performance of the proposed detector is superior to that of the frame detector based on cyclic autocorrection when message collisions exist.

      Small and large scale site diversity experiment at Ka-band in the south of France (pages 14–28)

      Xavier Boulanger, Frédéric Lacoste and Laurent Castanet

      Version of Record online: 9 SEP 2016 | DOI: 10.1002/sat.1190

      This article presents the results of the ONERA-CNES Ka-band site diversity experiment. The description of the experimental set-up and the statistical results from July 2013 to December 2014 are provided. The complementary cumulative distribution functions of rain attenuation and the joint distributions for several pairs of radio links are illustrated. Comparisons of the measured diversity gain with two prediction models are also presented.

      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.

      Tri-orthogonal polarization diversity reception for non-geosynchronous satellite orbit ionospheric channels (pages 44–65)

      Nicholas P. Lawrence, Hedley J. Hansen and Derek Abbott

      Version of Record online: 8 DEC 2016 | DOI: 10.1002/sat.1203

      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.

      Random access schemes for satellite networks, from VSAT to M2M: a survey (pages 66–107)

      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.

      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.

      Effect of raindrop size distribution and rain rate inhomogeneity on the relationship between attenuation and depolarization (pages 134–145)

      Depolarization due to rain is another factor that degrades satellite propagation signals, especially in the higher frequency bands and in places that have high rates of rainfall. A formula to predict cross-polarization as a function of attenuation has been proposed, and it is derived by a theoretical calculation using frequency, the forward scattering amplitude of raindrops, rainfall rates, the raindrop size distribution, and various other propagation parameters.

      This article presents an analytic study of Ka-band high-throughput-satellite (HTS) channel uplink signal-to-noise-plus-interference-ratio (SNIR). It addresses the SNIR distribution for mobiles and urban users and fills in the blank of the theoretic study of the problem.
