“…Second, we introduce a "Difficult" dataset, which contains all 24 modulations. These include a number of high order modulations (QAM256 and APSK256), which are used in the real world in very high-SNR low-fading channel environments such as on impulsive satellite links [25] (e.g. DVB-S2X).…”

We conduct an in depth study on the performance of deep learning based radio signal classification for radio communications signals. We consider a rigorous baseline method using higher order moments and strong boosted gradient tree classification and compare performance between the two approaches across a range of configurations and channel impairments. We consider the effects of carrier frequency offset, symbol rate, and multi-path fading in simulation and conduct over-the-air measurement of radio classification performance in the lab using software radios and compare performance and training strategies for both. Finally we conclude with a discussion of remaining problems, and design considerations for using such techniques.

“…Assuming that the operator is totally free to optimise the symbol rate to increase the spectral efficiency and an enhanced receiver, the investigations carried out during the system definition phase have shown that there is no clear benefit to use sharper roll‐offs . Although sharper roll‐offs may allow higher symbol rates, the additional capacity gain is generally negligible.…”

“…Nevertheless, the studies that have brought to the development of DVB‐S2X have evidenced the benefits offered by more advanced equalisers, allowing broadcasters more freedom to optimise the transmission to a higher symbol rate. Computer simulations on a realistic channel model , including IMUX and OMUX satellite filters (corresponding to a 38 MHz‐3 dB bandwidth and channel spacing of 40 MHz) and a faithful travelling wave tube amplifiers non‐linear model (including both amplitude and phase distortions), this model, also incorporating an element of adjacent channel interference in both the uplink and downlink paths and using free symbol rate optimisation with adaptive equalisation (in enhanced receivers), demonstrated spectral efficiency gains of around 7% to 9% over conventional receivers .…”

Digital Video Broadcasting-Satellite-Second Generation (DVB-S2) has been specified about 10 years ago, with a strong focus on Direct-to-Home, but interactive broadband applications (forward link), digital satellite news gathering and other professional links such as internet trunking were included. Since then, new requirements have come up, including extended efficiency and flexibility in the core applications of DVB-S2, with specific focus on ultra-high-definition television delivery to the home, using High Efficiency Video Coding, the new video coding technique jointly developed by ITU and MPEG, and new ones for emerging markets. DVB-S2X provides the necessary technical specifications for covering traditional DVB-S2 use cases and new ones for operating at very low signal-to-noise ratio down to À10 dB, such as mobile services for business jets, fast trains and boats, and low aperture terminals for journalists. This paper and the others in this special issue describe the details of the standard and its performance in the various application scenarios.

BACKGROUNDIn September 1993, the Digital Video Broadcasting (DVB) project was launched, with the purpose of promoting the switchover from analogue to digital television (TV) broadcasting. It was a private, market-driven association, including all the main actors in digital TV such as broadcasters, network operators, manufacturers and regulators.Thanks to the achievements in the field of digital VLSI technology, both in the transmission and in the source coding areas, the first milestone of the DVB project was the specification of DVB-S. This was DVB's digital, multi-programme, TV system for satellite broadcasting that together with the adoption of MPEG2, introduced satellite direct-to-home (DTH) digital TV.With the worldwide success of this system, it became clear that it could also be suitable for digital satellite news gathering (DSNG) applications, with significant advantages in cost, performance and flexibility over the previous systems. In the summer of 1997, the DVB Project decided to start the development of a new specification for DSNG, based on the DVB-S system but with a number of new features added to cover the commercial and operational requirements of contribution applications. At the same time, DVB-S became the basis of the so called 'DVB family', on which the first generation digital standards for cable (DVB-C) and terrestrial (DVB-T) broadcasting were built.In 2003, 10 years after the standardization of DVB-S, DVB-S2 [1] was the first physical layer system of a new generation of digital standards to be developed in the DVB family. It set the benchmark for technical excellence, drove the design concepts for terrestrial and cable applications and along with MPEG4, led the way for introduction of high-definition TV services. However, DVB-S2 was no longer only a system for DTH broadcasting, but one for interactivity (i.e. internet access) and professional services (e.g. TV contribution links and DSNG) as well. To be able to cover all the application areas, while still keeping the single-chip decoder at reasonable complexity levels, DVB-S2 was structured as a toolkit, thus enabling the use of mass market products for professional or niche applications.In 2013, 10 years after the development of DVB-S2, following a request by the Commercial and Technical Modules, the DVB-S2 group started to analyse a further evolution of satellite technologies to enhance performance in the core markets (DTH, contribution, Very Small Aperture Terminal (VSAT) and DSNG) and to increase the range of applications of the standard to cover emerging markets such as mobile (air, sea and rail) or professional applications. DVB-S2X: THE DVB-S2 EXTENSIONSThe DVB-S2X [2] is an extension of the DVB-S2 specification that provides additional technologies and features for the core applications of DVB-S2 including DTH, contribution, VSAT and DSNG. The specification also provides an extended operational range to cover emerging markets such as mobile applications.
