Riccardo De GaudenziRiccardo De Gaudenzi

Riccardo De Gaudenzi was born in Italy in 1960. He received his Doctor Engineer degree (cum Laude) in electronic engineering from the University of Pisa, Italy in 1985 and the PhD from the Technical University of Delft, The Netherlands in 1999. From 1986 to 1988 he was with the European Space Agency (ESA), Stations and Communications Engineering Department, Darmstadt (Germany) where he was involved in satellite telecommunication ground systems design and testing. In particular, he followed the development of two new ESA's satellite tracking systems. In 1988, he joined ESA’s Research and Technology Centre (ESTEC), Noordwijk, The Netherlands where in 2000 he has been appointed head of the Communication Systems Section and since 2005 he is Head of the RF Payload and Systems Division. The division is responsible for supporting the definition and development of advanced satellite system, subsystems and related technologies for telecommunications, navigation and earth observation applications. In 1996 he spent one year with Qualcomm Inc., San Diego USA, in the Globalstar LEO project system group under an ESA fellowship.  His current interest is mainly related with efficient digital modulation and multiple access techniques for fixed and mobile satellite services, synchronization topics, adaptive interference mitigation techniques and communication systems simulation techniques. He actively contributed to the development and the demonstration of the ETSI S-UMTS Family A, DVB-S2 and DVB-SH standards. From 2001 to 2005 he has been serving as Associate Editor for CDMA and Synchronization for IEEE Transactions on Communications. He is co-recipient of the 2003 and 2008 Jack Neubauer Memorial Award Best Paper from the IEEE Vehicular Technology Society.

The evolution of satellite communications - a signal processing perspective

Following 1945 A. C. Clarke intuition of the satellite Geostationary concept, satellite communication technology has been becoming a reality in the late 60’s making possible intercontinental voice and video communications. In the 70’s also mobile satellite telecommunications for maritime users became a reality. The development of satellite telecommunication technology has been driving the introduction of advanced coding schemes such as the Viterbi’s algorithm and multiple access schemes such as Time Division Multiple Access and associated burst mode demodulator. These two technologies were the base for the terrestrial GSM digital mobile standard which had an unprecedented commercial success.

Nowadays the technology pioneering role of satellite communications appears to be shadowed by the fast pace development of wireless terrestrial technologies. In this talk a review of most promising signal processing techniques adopted or candidate for being adopted in modern satellite networks. Differences in the satellite operating system conditions compared to terrestrial networks will be stressed as well as the required adaptationsof signal processing techniques.
