The research activities in this area are focused on the development, validation and study of techniques and algorithms for
a) adaptive estimation of digital signals and systems,
b) pattern recognition (classification and clustering) of signals and images,
c) spectral unmixing and classification of hyperspectral images,
d) compressive sensing and sparse signal representations,
e) processing of communication signals at the physical layer in the framework of conventional single-carrier transmission, multicarrier transmission and cooperative transmission and
f) performance evaluation of digital communication systems.
