Novel Symbol- and Frame-level Precoding Algorithms and Connections to Multicasting

Abstract: This seminar focuses on the latest advancements in MU-MISO downlink precoding. Two recent applications which target novel precoding scenarios are reviewed and connection to PHY-layer multicasting are revealed. More specifically, the first part addresses the concept of frame-based precoding which originates in practical standards dictating the grouping of multiple users in a single Forward Error Corrected frame. The second part reviews the field of constructive interference precoding, where the precoding takes place on a symbol-by-symbol basis taking into consideration both the user channel vector and its desired symbol. Finally, a number of promising but challenging open research topics are proposed.

Bio: Dr Symeon Chatzinotas (MEng, MSc, PhD, SMIEEE) received the M.Eng. in Telecommunications from Aristotle University of Thessaloniki, Greece and the M.Sc. and Ph.D. in Electronic Engineering from University of Surrey, UK in 2003, 2006 and 2009 respectively. He is currently a Research Scientist with the research group SIGCOM in the Interdisciplinary Centre for Security, Reliability and Trust, University of Luxembourg, managing H2020, ESA and FNR projects. In the past, he has worked in numerous R&D projects for the Institute of Informatics & Telecommunications, National Center for Scientific Research ?Demokritos,? the Institute of Telematics and Informatics, Center of Research and Technology Hellas and Mobile Communications Research Group, Center of Communication Systems Research, University of Surrey. He has authored more than 120 technical papers in refereed international journals, conferences and scientific books. His research interests are on multiuser information theory, cooperative/cognitive communications and wireless networks optimization. Dr Chatzinotas is the co-recipient of the 2014 Distinguished Contributions to Satellite Communications Award, Satellite and Space Communications Technical Committee, IEEE Communications Society. He is currently co-editing a book on "Cooperative and Cognitive Satellite Systems" to appear in 2015 by Elsevier and he is co-organizing the First International Workshop on ?Cognitive Radios and Networks for Spectrum Coexistence of Satellite and Terrestrial Systems? (CogRaN-Sat) in conjunction with the IEEE ICC 2015, 8-12 June 2015, London, UK.
