Special Issue Information

Dear Colleagues,

The role of satellite networks is of utmost importance for providing ubiquitous Internet services. Due to their broadcasting ability and global coverage at standard cost, satellites present an effective communication platform capable of relaying radio signals virtually between any points on Earth. In the upcoming 5G era, the future cellular and satellite communication networks should be envisioned to support efficient and flexible resources management and provide customized services to meet the service-specific high-performance requirements in a variety of use cases. New higher frequency bands are also allocated for employment in the future cellular and satellite networks in order to support the new challenging demands by the users that generally need more bandwidth. The propagation channel plays the most crucial role in order to provide reliable communications, high availability and determine the system dimensioning (number of antennas, relays, etc.). The novelty on which 5G communication systems will establish and will make the system to be more agile, smart and robust is the exploitation of the Software Defined Networks (SDN), the Network Function Virtualizations (NFV) and the Artificial Intelligence (including Machine and Deep Learning) techniques. Therefore, the role of satellites should be investigated for the provision of the main services of 5G systems such as enhanced Mobile Broadband (eMBB), Ultra reliable low latency communications (URLLC), and machine or massive type of communications (mTC) for Machine to machine (M2M) communications.

This Special Issue aims at collecting original studies on advanced satellite communication technologies innovative architectures that combine various modalities, experiments that deploy prototype satellite systems, and the exploration of new frequency bands and orbits.

The 5G vision embraces a broad range of applications including the connectivity in underserved and remote areas. In particular, for these applications, satellites are going to play a role in future 5G networks to provide capacity on trains, vessels, aircraft, and for base stations around the globe. In this paper, a 5G edge node concept, developed and evaluated with over-the-air tests using satellites in the geostationary orbit, is presented. The article covers a testbed demonstration study in Europe with a large-scale testbed including satellites and the latest standardization for the network architecture. The main goal of this testbed is to evaluate how satellite networks can be best integrated within the convergent 5G environment. The over-the-air tests for 5G satellite integration in this article are based on a 3GPP Release 15 core network architecture. Full article

Satellites can provide strong value-add and complementarity with the new cellular system of the fifth generation (5G) in cost-effective solutions for a massive number of users/devices/things. Due to the inherent broadcast nature of satellite communications, which assures access to remote areas and the support to a very large number of devices, satellite systems will gain a major role in the development of the Internet of Things (IoT) sector. In this vision, reliable multicast services via satellite can be provided to deliver the same content efficiently to multiple devices on the Earth, or for software updating to groups of cars in the Machine-to-Machine (M2M) context or for sending control messages to actuators/IoT embedded devices. The paper focuses on the Network coding (NC) techniques applied to a hybrid satellite/terrestrial network to support reliable multicast services. An energy optimization method is proposed based on joint adaptation of: (i) the repetition factor of data symbols on multiple subcarries of the transmitted orthogonal frequency division multiplexing (OFDM) signal; and (ii) the mean number of needed coded packets according to the requirements of each group and to the physical satellite links conditions.

Next generation 5G networks generate a need for broadband, low latency and power efficient backhauling and data-relay services. In this paper, optical satellite communications links, as an integrated component of 5G networks, are studied. More specifically, the Geostationary (GEO) satellite-to-ground optical communication link is investigated. Long-term irradiance statistics based on experimental measurements from the ARTEMIS program are presented and a new time series generator related to the received irradiance/power fluctuations due to atmospheric turbulence is reported. The proposed synthesizer takes into consideration the turbulence-induced scintillation effects that deteriorate the laser beam propagation, on the assumption of the Kolmogorov spectrum. The modeling is based on Rytov theory regarding weak turbulence conditions with the incorporation of first order stochastic differential equations. Summing up, the time series synthesizer is validated in terms of first and second order statistics with experimental results from the European Space Agency‘s ARTEMIS experimental optical downlink and simulated received power statistics for various weather conditions are presented using the proposed validated methodology. Some important conclusions are drawn. Full article
