Title: Signal Theory and Design for Wireless Transmission of Information and Power
Abstract: Radio waves carry both energy and information simultaneously. Nevertheless, RF transmission of these quantities have traditionally been treated separately. A paradigm shift in wireless network design consists in unifying wireless transmission of information and power so as to make the best use of the RF spectrum and radiations and the network infrastructure for the dual purpose of communicating and energizing. In this talk, we discuss recent progress on laying the foundations of the envisioned network by establishing a signal theory and design for wireless information and power transmission (WIPT) and identifying the fundamental trade-off between conveying information and power wirelessly. We start with an overview of WIPT challenges and technologies. We then discuss the energy harvester behaviours and show how WIPT signal and system design crucially revolves around the underlying energy harvester model. To that end, we highlight different energy harvester models, namely linear and nonlinear models, and show how WIPT designs differ for each of them in single-user and multi-user deployments. Topics discussed include rate-energy region characterization, transmitter and receiver architecture, waveform, modulation, beamforming, input distribution, resource allocation and RF spectrum use. We discuss and check the validity of the different energy harvester models and the resulting signal theory and design through circuit simulations, prototyping and experimentation. We also point out numerous directions that are promising for future research.
Bio: Bruno Clerckx is a Reader (Associate Professor) in the Electrical and Electronic Engineering Department at Imperial College London (London, United Kingdom). He received his M.S. and Ph.D. degree in applied science from the Université catholique de Louvain (Louvain-la-Neuve, Belgium) in 2000 and 2005, respectively. From 2006 to 2011, he was with Samsung Electronics (Suwon, South Korea) where he actively contributed to 3GPP LTE/LTE-A and IEEE 802.16m and acted as the rapporteur for the 3GPP Coordinated Multi-Point (CoMP) Study Item. Since 2011, he has been with Imperial College London, first as a Lecturer (2011-2015), then as a Senior Lecturer (2015-2017), and now as a Reader. From March 2014 to March 2016, he also occupied an Associate Professor position at Korea University, Seoul, Korea. He also held visiting research appointments at Stanford University, EURECOM, National University of Singapore and The University of Hong Kong.
He is the author of 2 books, 150 peer-reviewed international research papers, 150 standard contributions and the inventor of 75 issued or pending patents among which 15 have been adopted in the specifications of 4G (3GPP LTE/LTE-A and IEEE 802.16m) standards. Dr. Clerckx served as an editor for IEEE TRANSACTIONS ON COMMUNICATIONS from 2011-2015 and is currently an editor for IEEE TRANSACTIONS ON WIRELESS COMMUNICATIONS and IEEE TRANSACTIONS ON SIGNAL PROCESSING. He has been TPC member, symposium chair, TPC chair of many symposia on communication theory, signal processing for communication and wireless communication for several leading international IEEE conferences. He has also been (lead) guest editor for EURASIP Journal on Wireless Communications and Networking, IEEE Access and IEEE Journal on Selected Areas in Communications. He was the editor for 3GPP LTE-Advanced standard technical report on CoMP. He is an Elected Member of the IEEE Signal Processing Society SPCOM Technical Committee. His research area is communication theory and signal processing for wireless networks.
