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 ...

Lattice codes for many-to-one cognitive interference networks

Michael Christoph Gastpar, Jingge Zhu

In this work we consider the cognitive many-to-one interference network. We first extend existing coding schemes from the two-user case to this network scenario. Then we present a novel coding scheme using compute-and-forward and show it can enlarge the ac ...

Unit Cell for Frequency-Tunable Beamscanning Reflectarrays

Julien Perruisseau-Carrier, Daniel Rodrigo Lopez

A reflectarray cell able to dynamically control the reflection phase at a variable frequency is presented. This capability enables beam-scanning reflectarrays with frequency reconfigurability, which is a novel capability with applications in frequency-hopp ...

Towards reconfigurable RF devices based on dielectric elastomer actuators

Herbert Shea, Julien Perruisseau-Carrier, Samuel Rosset, Pietro Romano, Oluwaseun Adelowo Araromi

Radio Frequency (RF) devices generate or control the transmission or reception of electromagnetic (EM) waves such as are used in mobile phones, WIFI etc. Microwave (MW) and millimeter‐wave (MMW) devices are used widely in satellite communications. Dynamic ...

Compressive Source Separation: Theory and Methods for Hyperspectral Imaging

Pierre Vandergheynst, Mohammad Golbabaee

With the development of numbers of high resolution data acquisition systems and the global requirement to lower the energy consumption, the development of efficient sensing techniques becomes critical. Recently, Compressed Sampling (CS) techniques, which e ...

User Effects in Beam-Space MIMO

Julien Perruisseau-Carrier, Mohsen Yousefbeiki, Halima Najibi

The performance and design of the novel single-RF-chain beam-space MIMO antenna concept is evaluated for the first time in the presence of the user. First, the variations of different performance parameters are evaluated when placing a beam-space MIMO ante ...

A Parallelized Layered QC-LDPC Decoder for IEEE 802.11ad

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Alessandro Cevrero, Nicholas Alexander Preyss

We present a doubly parallelized layered quasi-cyclic low density parity-check decoder for the emerging IEEE 802.11ad multigigabit wireless standard. The decoding algorithm is equivalent to a nonparallelized layered decoder and, thus, retains its favorable ...

Novel approach to the measurement of ultra wideband antenna efficiency

Anja Skrivervik, Nuno Miguel Faria Pires, Mohsen Koohestani

This Letter presents a new cavity-based approach for measuring the radiation efficiency of Ultra Wideband (UWB) antennas. The procedure is based on a generalized Wheeler cap method (GWCM ) that is only practical for narrowband measurements and so this Lett ...
