Xavier Mestre is currently a Research Director (R4) at CTTC.

He received the MS and PhD in Electrical Engineering from the Technical University of Catalonia (UPC) in 1997 and 2002 respectively and the licenciate (5 year) degree in Mathematics in 2011. During the pursuit of his PhD, he was recipient of a 1998-2001 PhD scholarship (granted by the Catalan Government) and was awarded the 2002 Rosina Ribalta second prize for the best doctoral thesis project within areas of Information Technologies and Communications by the Epson Iberica foundation.

From January 1998 to December 2002, he was with UPC’s Communications Signal Processing Group, where he worked as a Research Assistant (1998-2000) and Research Associate (2001-2002) and participated actively in several European-funded projects (ACTS Sumbeam, IST METRA, IST I-METRA and MEDEA+ UNILAN) as well as several national projects. In January 2003 he joined the Telecommunications Technological Center of Catalonia (CTTC), where he currently holds a position as a Senior Research Associate. During this time, he has actively participated in 12 European projects, four times as Principal Investigator (PI): H2020 Windmill (PI), FP7 EMPhAtiC (PI), CELTIC SAN (PI), FP6 COOPCOM (PI), H2020 FANTASTIC-5G, FP7 Advantage, FP7 NEWCOM#, FP7 NEWCOM++, FP6 ACE 2, IST ACE, IST Newcom, MEDEA+ Marquis. In particular, he was the project coordinator of the European ICT project EMPhAtiC (2012-15). He has participated in 5 industrial contracts, four times as a PI, namely: Upstart (PI), Radpark (PI), MUMO (PI), MUMO 2 (PI) and MUMIMO PLC. The results of some of these contracts have been developed into commercialized products. He has participated in two ESA contracts (Coupled ETC, MIMO-SAT) and 7 projects funded by the Spanish Government (as PI in three of them): 5G-Lab (PI), TEC GRE3N (PI), TEC FBMC-SILAN (PI), TEC Elisa, CENIT ENERGOS, CENIT GAD, Mercure. He is author of three granted patents owned by CTTC and one patent owned by Huawei Technologies. He is author of 66 deliverables and technical reports, as well as two industrial white papers. He has been PI of four fellowships to the Consolidated Research Groups granted by the Catalan Government (SGR), years 2017, 2014, 2009 and 2005. Since 2017 he has been adjunct lecturer at the Engineering Department of the Universitat Autònoma de Barcelona.

From the scientific point of view, he has edited a book published by Elsevier and is author of 9 book chapters, 48 international journal papers and more than 105 articles in international conferences. He is co-author of the 2020 EURASIP Journal on Wireless Communications and Networking Best Paper Award and the 2016 IEEE Workshop on Statistical Signal Processing Best Student Paper Award. He has advised 5 PhD thesis (two still ongoing), funded by grants given by the Spanish Government (1), the Catalan Government (2) and the European Commission (2). He has been invited to give 10 keynote talks on topics of his own research at several international research institutes and Universities. He has organized four special sessions and chaired more than 10 technical sessions in international conferences.

He has been Associate Editor of the IEEE Transactions on Signal Processing for two terms (2008-11, 2015-2019), Senior Area Editor of the same journal (2019-present) and associate co-editor of the special issue on at the EURASIP Journal on Wireless Communications and Networking. He is IEEE Senior member and elected member of the IEEE Sensor Array and Multi-channel Signal Processing Technical Committee (2013-2018), the IEEE Signal Processing Theory and Methods Technical Committee (2019-present), the EURASIP Technical Area Committee on Signal Processing in Communications (2018-present) and the EURASIP Technical Area Committee on Theoretical and Methodological Trends in Signal Processing (2015-present). Since 2019 where he is also vice-chair of this last Technical Area Committee. He has been regular member of the evaluation committee of the Spanish Ministry of Science and Education, the Catalan Department of Research and Universities (AGAUR), the Agence National de la Recherche (ANR, France) and several universities (Instituto de Telecomunicações, Université Paris Saclay).

He has participated in the organization of multiple conferences and scientific events, such as the “IEEE Wireless Communications and Networking Conference 2018″ (general vice-chair), the “IEEE International Symposium on Power Line Communications” (technical chair), the “European Wireless 2014″ (general co-chair), the “European Signal Processing Conference 2011″ (general technical chair), the “IEEE Winter School on Information Theory” 2011 (general co-chair), the “Summer School on Random Matrix Theory for Wireless Communications” 2006 (general chair). He was general chair of the IEEE International Conference on Acoustics, Speech and Signal Processing 2020 and will also be general chair of the 2026 edition of this conference.
