Daniel Roviras

Professeur Cnam
Office: 11B2-37

Dr. Daniel Roviras got his Engineer degree from SUPELEC in 1981. After 7 years spent in industry as a Research Engineer, he joined the Electronics Laboratory of ENSEEIHT (Toulouse, France) and got his Ph.D. degree in 1989. He joined the Engineering school ENSEEIHT in 1992 as an Assistant Professor and he is Full Professor since 1999. Since 2008, he is professor in Conservatoire National des Arts et Métiers (Paris, France) where his teaching activities are related to Radio-communication systems. His research activities have been first centered around transmission systems based on infrared links. Since 1992, his topics have widened to more general communication systems as mobile and satellite communications systems, equalization and predistorsion of non-linear amplifiers, multiple access methods, multicarrier waveforms and massive MIMO systems. He is currently member of LAETITIA laboratory in CNAM.
