Xavier Mestre is currently a Senior Researcher at CTTC (Head of the Advanced Signal and Information Processing Department). 

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.

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 13 PhD evaluation committees at UPC (7), Supelec (2), Télécom ParisTech (1), Université Marne-la-Vallée (1), Université catholique de Louvain (1) and Klagenfurt University (1).

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, to be held in Barcelona.

His current research interests include: Signal processing for communications, array processing, massive MIMO architectures and large random matrices.
