A Versatile Spectrum Shaping Scheme for Communicating Beyond Notches in Multi-Drop Interfaces”

Mohammad Amin Shokrollahi, Seyed Armin Tajalli, Christoph Walter, Ali Hormati, Kiarash Gharibdoust

This paper proposes a signal shaping technique to increase the data rate of high-speed SerDes communication systems over multi-drop bus interfaces. This scenario creates a channel with deep notches in its spectrum, and therefore the effective data rate in ...

On Flexibeam for radio interferometry

Paul Hurley, Matthieu Martin Jean-André Simeoni

Beamforming in radio astronomy focuses at and around a direction using matched beamforming or a derivative, to both maximise the energy coming from this point and reduce the data rate to the central processor. Such beamformers often result in large side-lo ...

Classical beamforming methods, based on Delay- And-Sum (DAS) require an extensive number of samples and delay calculations to obtain high-quality images. Compressed Beamforming (CB) proposes an alternative to DAS, based on compressed sensing, which aims at ...

Multi-Terabit/s Transmission Using Chip-Scale Frequency Comb Sources

Tobias Kippenberg, Victor Brasch, Tobias Herr

Chip-scale frequency comb sources are likely to become key elements of future terabit/s optical transceivers. We investigate and demonstrate the viability of different comb generation schemes for transmission at multiterabit/s data rates. ...

Ultra Low-Power Frequency Synthesizers for Duty Cycled IoT radios

Raghavasimhan Thirunarayanan

Internet of Things (IoT), which is one of the main talking points in the electronics industry today, consists of a number of highly miniaturized sensors and actuators which sense the physical environment around us and communicate that information to a cent ...

Optimal Selection of Adaptive Streaming Representations

Pascal Frossard, Laura Toni

Adaptive streaming addresses the increasing and heterogenous demand of multimedia content over the Internet by offering several encoded versions for each video sequence. Each version (or representation) has a different resolution and bit rate, aimed at a s ...

A Low-Power PPM Demodulator for Remotely Powered Batteryless Implantable Devices

Catherine Dehollain, Enver Gürhan Kilinç, Franco Maloberti

A low-power PPM demodulator has been developed for remotely powered batteryless implantable devices. The required power is harvested by the magnetic coupling with external powering coils placed under the living space of the animal. The remote powering is t ...

A 240x180 120dB 10mW 12us-latency sparse output vision sensor for mobile applications

This paper proposes a CMOS vision sensor that combines event-driven asychronous readout of temporal contrast with synchronous frams-based active pixel sensor (APS) readout of intensity. The image frames can be used for scene content analysis and the tempor ...

Device-to-Device Assisted Video Transmission

Laura Toni, Wenwen Zhou

To increase spectrum efficiency, researchers envi- sion a device-to-device (D2D) communication system in which a closely located mobile device pair may share the same spectrum with a cellular user. By opportunistically choosing the frequency, the D2D pair ...
