Cognitive Radio Applications for Wireless Multimedia - Technology and Testbed

 

Abstract

The enormous growth of wireless multimedia applications over the wireless Internet is a trend that is expected to continue also for the future. The need for ubiquitous wireless services has come from using only a small part of the wireless spectrum, nominally less than 10% under 3 GHz. There is growing evidence of scarcity and overcrowding in these bands reflected, for example, by the price paid for the 3G spectrum (€ 90 billion in Europe). The Cognitive Radio paradigm promises to be one of the principles for more efficient spectrum utilization, relying on dynamic spectrum access, spectrum sharing, utilization of white spaces and adaptive transmissions. Cognitive radio adds adaptability to the wireless services smoothing the gap between the current fixed frequency allocation plan and the demands of modern multimedia - related wireless services. Therefore, cognitive radio represents a great potential for wireless multimedia services and is one of the main researching topics in the field of wireless technologies. The goal of the present tutorial is to give a general description of the technology behind the cognitive radio networks in terms of basic theoretical concepts such as spectrum sensing and adaptive transmission, as well as possible architectures and practical aspects relevant to implementation for wireless multimedia applications.

   
 

Bio
Vlad Popescu received the M.Sc. degree in Electronic and Computer Engineering in 1999 and the PhD degree in Telecommunications in 2006, both from the Transilvania University of Brasov / Romania. In 2001 / 2002 he spent one year as a research fellow at the Technical University in Aachen (RWTH) / Germany. In 2004 / 2005 he returned to Aachen at the same University to finish his PhD studies with a DAAD Scholarship. At present, he is a lecturer in Electronics at the Dept. of Electronics and Computers, Transilvania University of Brasov and collaborates close with the Dept. of Electrical and Electronic Engineering, University of Cagliari. His main research topics of interest are telecommunications, multimedia and data acquisition.

The future of Terrestrial Broadcasting in Europe

Abstract

This tutorial will present the technology trends in the field of terrestrial broadcasting in Europe. The tutorial will review the current state-of-the-art, showing a picture of the different standards and frequency bands for mobile, fixed, cabled and satellite broadcast systems. The tutorial will provide an overview of the future standards for terrestrial broadcasting, emphasizing the technologies enable an optimization of the use of the spectrum assinged to broadcasting in the UHF band. The new services upcoming in the following years (enhanced HDTV formats and 3DTV) will be also covered. A section will be dedicated to mobile and portable services. Finally, an overview of the potential usage scenarios of the UHF broadcast band will be given, showing the pros and cons of each use case and the possible implications in the broadcast services as we know them today.


Bio
Pablo Angueira (IEEE Senior Member) received the M.S. and PhD in Telecommunication Engineering at the University of the Basque Country (Spain) in 1997 and 2002 respectively. Prof. Pablo Angueira joined the Dpt. of Electronics and Telecommunications of the University of the Basque Country in 1998. Within the TSR Research Group, he has been involved for 10 years in research projects to evaluate digital broadcasting systems in different frequency bands. His current research activities are related to DRM and new broadcast technologies (DVB-T2 and NGH). Pablo Angueira is co-author of a wide list of international peer reviewed journals, conference presentations related to digital terrestrial broadcast planning. He has supervised several PhD dissertations in this field. He has also co-authored contributions to the ITU-R working groups WP6 and WP3. Dr. Angueira is an Associate Editor of the IEEE Transactions on Broadcasting journal and Chairs the Strategic Planning Committee of the Broadcast Technology Society Administrative Committee.
He is senior member of the IEEE and member of many international program committees. He has organized many conferences, chaired several technical sessions and gave tutorials at major international conferences.
