Method of real-time regulation compliance for wireless transmitters

Pierre-André Farine, Alexis Boegli, Mitko Tanevski

All wireless devices must comply with the local radio regulations which are set by international and national regulatory bodies such as the European Telecommunication Standardization Institute (ETSI) for Europe and the Federal Commission for Communication ...

Design optimization of polyphase digital down converters for extremely high frequency wireless communications

Yusuf Leblebici, Gain Kim, Raffaele Capoccia

In this paper, an area-optimized polyphase digital down converter (DDC) architecture is introduced, where the mixers can be completely merged into the polyphase decimation filter under certain conditions. We also introduce an interface architecture, called ...

Binaural hearing aids with wireless microphone systems including speaker localization and spatialization

Hervé Lissek, Patrick Marmaroli, Gilles André Courtois

The digital wireless microphone systems for hearing aids have been developed to provide a clean and intelligible speech signal to hearing-impaired listeners for e.g. school or teleconference applications. In this technology, the voice of the speaker is pic ...

Power-Efficient Joint Compressed Sensing of Multi-Lead ECG Signals

David Atienza Alonso, Pierre Vandergheynst, Giovanni Ansaloni, Hossein Mamaghanian

Compressed Sensing (CS) is a new acquisition- compression paradigm for low-complexity energy-aware sensing and compression. By merging both sampling and compression, CS is very promising to develop practical ultra-low power read- out systems for wireless b ...

Model-Based Design for Wireless Body Sensor Network Nodes

David Atienza Alonso, Francisco Javier Rincon Vallejos, Nadia Khaled, Ivan Beretta

Wireless body sensor networks (WBSNs) are a rising technology that allows constant and unobtrusive monitoring of the vital signals of a patient. The configuration of a WBSN node proves to be critical in order to maximize its lifetime, while meeting the pre ...

On the Exploitation of the Inherent Error Resilience of Wireless Systems under Unreliable Silicon

Andreas Peter Burg, Georgios Karakonstantis

In this paper, we investigate the impact of circuit misbehavior due to parametric variations and voltage scaling on the performance of wireless communication systems. Our study reveals the inherent error resilience of such systems and argues that sufficien ...

A Flexible In Situ Power Monitoring Unit for Environmental Sensor Networks

Alcherio Martinoli, Alexander Bahr, William Christopher Evans

Wireless radios are a great consumer of energy in sensor networks. Retrieving data from a remote deployment in an energy-efficient fashion is a difficult problem, and while solutions have been proposed in literature, real-world systems typically implement ...

Reconfigurable parasitic antennas for compact mobile terminals in multiuser wireless systems

Julien Perruisseau-Carrier

This article considers the exploitation of parasitic antenna arrays in multi-user (MU) wireless communication systems by using their adaptive beamforming capabilities in order to improve the average system throughput. The use of parasitic arrays and especi ...
