Chapter
On-ground beam forming (OGBF) is an advanced signal processing technique which has been recently brought to the attention of the SatCom community thanks to its ample use in advanced mobile satellite systems. The interest in this technique is motivated by multiple reasons: beam forming is required to achieve good antenna performances in L- and S-ban...
Conference Paper
This papers addresses the design of new energy-efficient Continuous Phase Modulation (CPM) waveforms suitable for being adopted in satellite mesh networks that are characterized by the absence of the Hub, and by small antennas and power amplifiers with moderate to low output saturated power at the user terminal. In particular, a CPM modulation form...
Article
This paper presents the field test results of the novel SkyMedia 3D/HD system in a marathon race setup. The augmentation system is tailored for immersive media experiences such as public live events in which people can interact together in order to improve user's experience. The paper reports the first public demonstration of the HD/3D content augm...
Conference Paper
In the satellite communications component of the future Internet, peer-to-peer mesh connectivity of satellite terminals is an impellent necessity. In particular, delay sensitive applications such as real-time multimedia, collaborative conferencing and cellular backhauling are appealing use-cases for adopting mesh network topologies. Moreover, the u...
Chapter
In the future, the increasing and continuous demand of services anytime and anywhere and, therefore, the mandatory globalization of mobile and wireless communications for next generation networks services will require a more and more efficient use of the scarce radio spectrum resources. The traditional communication systems which imply an a priori...
Conference Paper
Full-text available
The radio resource shortage is one of the most important characteristic to take into account when deploying modern wireless telecommunication systems. A novel communication paradigm named Cognitive Radio, has been introduced in the last years for better exploiting the limited available spectrum and the inefficiency in the spectrum usage. Its main a...
Article
In this paper, we describe how satellite communications may contribute to disaster management. During emergency situations, satellite communications present many advantages in supporting or replacing a terrestrial infrastructure (if any) subject to destruction or saturation. However, devising the right deployment model deserves close scrutiny in or...
Conference Paper
In the entertainment industry, technology advances are continuously improving and evolving the portfolio of services and distinguished features that can be experienced by the audience, whether it is attending the event on site or remotely. In this context, the SkyMedia system aims at exploring, designing, and demonstrating a novel multimedia end-to...
Conference Paper

This paper proposes a novel, interactive telemedicine platform, providing real-time audio and video interactions among patients, physicians and health service provider. Such a system has been developed within the framework of the European Space Agency (ESA) project TElemedicine Services for HEALTH (TESHEALTH) in collaboration among industry, academ...
Conference Paper
This paper reports a study concerning the assessment of cooperation effects at MAC layer in DVB-RCS systems. In particular, a modified resource allocation mechanism has been considered in order to implement a Selective Forwarding cooperation scheme within a group of sources working in a land-vehicular scenario. The achieved results are presented in...
Chapter
Full-text available
This chapter has presented the possible adoption of cooperation strategies in satellite access, focusing on two case studies showing an uplink and downlink mobile satellite scenario. The use of these different techniques and methodologies in various applications scenarios, can led to the achievement of improvement of the system performance in terms...
Conference Paper
This paper describes the SALICE (Satellite-Assisted LocalIzation and Communication systems for Emergency services) project, an Italian National Research Project which has been recently funded by the Italian Ministry of Research; the SALICE project aims at identifying the solutions which can be adopted in an integrated reconfigurable NAV/COM device...
Conference Paper
Full-text available
The integration of satellite and terrestrial systems in a hybrid network permits to benefit from both systems, overcoming the drawbacks of a Non-Line-Of-Sight (NLOS) propagation. The purpose of this paper is to study simple cooperative relaying strategies which rely on the introduction of the Delay Diversity (DD) technique in a DVB-SH compliant hyb...
Conference Paper
Alert systems are key elements for effective management of a disaster. They are used to alert citizens and professional responders. Alert systems should be robust, multi-modal and simple. Satellites are resilient to Earth damages and display an inherent broadcast capability. For these reasons, satellite systems are suited for alert systems either a...
Conference Paper
The Cognitive Radio approach can be considered as a promising and suitable solution to solve in an efficient and flexible way the increasing and continuous demand of services and radio resources. This paper investigates how the adoption of a cognitive radio strategy can help in the coexistence problem of two wireless networks operating on the same...
Article
Cognitive Radio (CR) approach can be considered as a promising and suitable solution to solve in an efficient and flexible way the increasing and continuous demand of services and radio resources. This paper shows the potential benefits of the adoption of a cognitive radio strategy to the coexistence problem. Two different approaches have been cons...
Conference Paper
This paper presents the study of an innovative satellite-terrestrial platform integrated with a Learning Management System (LMS) for distance learning applications, aligned with the latest educational requirements and implementing the most advanced technological solutions, with special attention to Open Source tools. The work represents part of the...

Abstract—Traditional communication,systems imply an a pri- ori association of the frequency band, the service assigned to it and,the used technology. Breaking this static association can provide much more flexible, efficient and easy-to-use dynamic systems,able to cope,with the requirements,and,constraints,of the environment,and users. Cognitive Ra...
