IoT waveforms for LEO satellite communications



T-3 IoT waveforms for LEO satellite communications

Prof. Guillaume Ferré
Univ. of Bordeaux, France

The concept of the Internet of Things has revolutionized many sectors of activity. Many communication technologies have been developed in recent years, in particular to enable long-range communications with low energy consumption. In order to be connected to the Internet, an object must be within communication range of a gateway. In 2020, it is estimated that 25% of the earth's surface is connectable to the Internet. In the 75% of the land surface not connected to the Internet are many farms. One solution to connect the entire surface of the earth is to use a constellation of Low Earth Orbit (LEO) satellites. The objective of this tutorial is to present the issues related to the implementation of LEO satellite IoT communications and to provide a comparative analysis of the techniques that can be used. 


Prof. Guillaume Ferré

Dr. Guillaume Ferré graduated in electronic and telecommunication engineering (ENSIL) at the University of Limoges (France) in 2003 and received the Ph.D. degree in 2006 from the Limoges University of Technology in the field of digital communications and signal processing. From 2006 to 2008 he was postdoctoral researcher at the Limoges XLIM laboratory and then at the IMS laboratory in Bordeaux. Since 2008 he is associate professor at ENSEIRB-MATMECA, an engineering school of Bordeaux INP. After several administrative responsibilities in the Telecommunications Department of ENSEIRB-MATMECA, Guillaume Ferré is now the Director of Industrial Relations at ENSEIRB-MATMECA. He carries out his research activities within the IMS laboratory in the "signal and image" team. These fields of research concern the circuits and systems for digital communications, it includes:

- Signal processing and digital communications for 5G and IoT

- Digital enhancement for wideband power amplifiers and time interleaved analog to digital converters.

Guillaume Ferré is the author of more than a hundred papers in international conferences. He is also author of 7 patents. He currently supervises 5 PhD students with a significant part of industrial research activities. He is member of several Technical Program Committees (ICC, Globecom, ICT, ICECS, etc.). In 2019, he received as author the Best Paper Award at the IEEE International Symposium on Personal, Indoor and Mobile Radio Communications (IEEE PIMRC 2019), Track 4, entitled "An Enhanced LoRa-Like Receiver for the Simultaneous Reception of Two Interfering Signals" In the IMS laboratory he holds the position of Vice-President of the Scientific Council. He is the Principal Investigator (PI) of many national and international projects, at the local level he is responsible for two research activities related to IoT, including one to investigate on the smart campus.
