Design and Implementation of a Neural Network Based Predistorter for Enhanced Mobile Broadband

Alexios Konstantinos Balatsoukas Stimming

Digital predistortion is the process of using digital signal processing to correct nonlinearities caused by the analog RF front-end of a wireless transmitter. These nonlinearities contribute to adjacent channel leakage, degrade the error vector magnitude o ...

Versatile spectral modulation of a broadband source for digital holographic microscopy

Christophe Moser, Tristan Colomb, Gaël Nardin

We demonstrate the potential of spatial light modulators for the spectral control of a broadband source in digital holographic microscopy. Used in a ‘pulse-shaping’ geometry, the spatial light modulator provides a versatile control over the bandwidth and w ...

Padoc: Enabling social networking in proximity

Denis Gillet, Adrian Christian Holzer, Jonny Quarta, Sven Reber

Apps supporting social networking in proximity are gaining momentum as they enable both augmenting face-to-face interaction with a digital channel (e.g. classroom interaction systems) and augmenting digital interaction by providing a local real life feelin ...
