Experimental characterization of Sigma Delta Radio over fiber system for 5G C-RAN downlink
ICT Express, 2020 Radio over Fiber is a promising technology for the 5G Cloud Radio Access Network. We demonstrate experimentally Sigma Delta Radio over Fiber by means of Sigma Delta Modulator (SDM) subsequently replacing expensive digital to analog converters.

Characterizing Alzheimer's disease severity via resting-awake EEG amplitude modulation analysis.
PLoS ONE, 2013 Changes in electroencephalography (EEG) amplitude modulations have recently been linked with early-stage Alzheimer's disease (AD). Existing tools available to perform such analysis (e.g., detrended fluctuation analysis), however, provide limited gains in
