Talk: Frederic Guilloud (January 12, 2017 at 11:00 am, LNT Library N2405)
On January 12, 2017 at 11:00 am, Frederic Guilloud from Telecom Bretagne will be giving a talk in the LNT Library N2405 about "Continuous Phase Modulation: a "new" waveform for 5G Massive Machine-Type Communications".
Continuous Phase Modulation: a "new" waveform for 5G Massive Machine-Type Communications
Among the new specifications of the future 5G wireless communication era, communications between machines reveals new technical challenges to take up. Radio access for IoT, or Wireless Sensor Networks, are among the most popular applications of machine-type communications. They are to be deployed where wired communications are lacking and where the energy distribution network is hardly available. Hence, most of the transmitters are battery-powered without any chance to be changed. In this context, how to save the energy consumption in order to increase the battery lifetime as long as possible?
On the physical layer, several new waveforms are competing for the upcoming 5G standardization, all of them being based on filtered multi-carrier modulations. However, the important signal peak power exhibited by multi-carrier modulations has a huge impact on the battery life and should prevent their implementation on the uplink. This talk will show why continuous phase modulations (CPM) can be an interesting alternative to multi-carrier waveforms for IoT and Wireless Sensor Networks. Some issues raised when dealing with CPM will also be presented together with some perspectives on possible solutions.
Frederic Guilloud received the Engineering degree in Electronics from the Ecole Nationale Supérieure de l'Electronique et de ses Applications (ENSEA), France, in 1998, and is a former student of the Ecole Normale Supérieure de Cachan (ENS Cachan). He received the Ph.D. degree in 2004 from Telecom ParisTech in Signal and Communications, entitled "Generic Architecture for LDPC Codes Decoding", and the HDR (french habilitation) from the University of Western Brittany in 2016.
Frederic Guilloud is "Professeur Agrégé" in electronics and power electronics since 1999, and Associate Professor at Telecom Bretagne in the Signal and Communications department since 2004. His research and teaching activities are focused on error correcting codes and digital communications including constant amplitude phase modulations, with a special emphasis on short frame communications.
