Design Techniques for High-Speed Multi-Level Viterbi Detectors and Trellis-Coded-Modulation Decoders

Andreas Peter Burg, Thomas Toifl, Lukas Kull

The implementation of a 25.6-Gb/s four-level pulse-amplitude-modulation (4-PAM) reduced-state sliding-block Viterbi detector (VD) is presented. The power consumption of the VD is 105 orilV at a supply voltage of 0.7 V, corresponding to an energy efficiency ...

High-Speed Wireline Link Design

Hazar Yüksel

High-speed serial links are a crucial application of semiconductor technology and have been the enabler of the scaling of computing systems. The increasing data-rate requirements of these links have only been partially satisfied by advancements in process ...

Electrophysiological correlates of visual backward masking in first-episode psychosis

Michael Herzog, Maya Roinishvili, Albulena Jashari-Shaqiri, Janir Nuno Ramos Antunes Da Cruz, Ophélie Gladys Favrod

Schizophrenia is a heterogeneous disorder and among other symptoms, patients have important visual impairments. Visual paradigms are therefore important tools to investigate the mechanisms of schizophrenia. We have previously shown that visual backward mas ...

An Approach to a Phase Model for Steady State Visually Evoked Potentials

José del Rocio Millán Ruiz, Ricardo Andres Chavarriaga Lozano

One of the most used signals in Brain Machine Interfaces (BMI) is the Steady State Visually Evoked Potentials (SSVEP). In a SSVEP-based BMI, a visual stimulus that flickers in a constant frequency is presented to the user, and the system has to detect if t ...

A photonic circuit for complementary frequency shifting, in-phase quadrature/single sideband modulation and frequency multiplication: analysis and integration feasibility

Jianqi Hu

A novel photonic integrated circuit architecture for implementing orthogonal frequency division multiplexing by means of photonic generation of phase-correlated sub-carriers is proposed. The circuit can also be used for implementing complex modulation, fre ...

Estimation Bounds for GNSS Synthetic Aperture Techniques

Pierre-André Farine, Cyril Botteron, Miguel Angel Ribot Sanfelix, Joaquin Cabeza de Pablo

This paper characterizes the estimation performance of synthetic aperture (SA) techniques in the context of moving GNSS receivers. Under the assumption of a stationary channel, SA techniques transform a single antenna into a virtual array. We first introdu ...

Neural correlates of visual backward masking in psychosis

Michael Herzog, Maya Roinishvili, Christine Mohr, Albulena Jashari-Shaqiri, Janir Nuno Ramos Antunes Da Cruz, Ophélie Gladys Favrod

In visual backward masking (VBM), a target is followed by a mask, which deteriorates performance on the target. Schizophrenia and first episodes patients show strong behavioral deficits, reflected in strongly reduced amplitudes of the EEG as compared to co ...

Usefulness of ambient-vibration measurements for seismic assessment of existing structures

Ian Smith, Pierino Lestuzzi, Yves Sylvain Gilles Reuland

A large number of buildings in regions with low to medium seismic hazard have been designed without considering earthquake actions. Retrofitting of all buildings that fail to meet modern code requirements is economically, technically and environmentally un ...

Structured amplitude and phase fields behind microstructures: The quest for high contrast modulation at proximity

Hans Peter Herzig, Toralf Scharf, Myun Sik Kim, Johana Bernasconi, Krishnaparvathy Puthankovilakam

Microstructures can be used to realize repetitive and singular high contrast features at different distances behind a structure. For practical applications, the amplitude field needs to be considered. To realize defined amplitude features at long distances ...
