Biography

Carles Fernández Prades received his M.Sc. degree in electrical engineering (with highest honours) from the Technical University of Catalonia (UPC), Barcelona, Spain, in 2000. In 2001, he was recipient of a Ministry of Education grant to work towards his Ph.D. degree and joined the Signal Processing and Communications group at UPC as a research assistant, getting involved in European (EMILY) and Spanish (TECNAV) research projects. In 2002, he engaged an educational innovation project funded by the Catalan Government. In 2003 he became the technical manager at UPC for an European Space Agency research related to the Search and Rescue service to be included in Galileo. His primary areas of interest include statistical and array signal processing, estimation theory, GNSS synchronization and digital communications.
