Expertise: Optical and wireless communications
Prof. Piazza’s research activities are in the areas of circuit theory and Digital Signal Processing (DSP) including adaptive algorithms and circuits, Artificial Neural Networks (ANN), multimedia, speech and audio processing. In the DSP and ANN areas, since 1988 he worked on linear and nonlinear modeling, identification, prediction, filtering of discrete-time signals, with specific topics on adaptive activation functions, complex-valued ANN, temporal dynamic ANN, unsupervised ANN. In the speech and digital audio areas, he worked on nonlinear speech processing, hand-free communication, sound quality evaluation/enhancement, noise reduction, audio metadata processing, blind audio source separation/deconvolution (linear and nonlinear).
Francesco Piazza received his Italian Laurea with honors in Electronic Engineering from the University of Ancona (now Polytechnical Univ. of Marche UNIVPM), Italy, in 1981. He worked at the Olivetti OSAI software development center (Ivrea, Italy) and then started his academic career at the the same University where is now full professor of Electrical Science.
