On the Duality between Multiple-Access Codes and Computation Codes

Michael Christoph Gastpar, Sung Hoon Lim, Jingge Zhu

For a two-user Gaussian multiple access channel, computation codes are designed for the scenarios where the decoder is not interested in decoding the two codewords, but only the sum of them. It has been observed that good computation codes should possess s ...

Low-profile multi-function antenna system for small satellites

Juan Ramon Mosig, Frédéric Bongard, Nevena Saponjic, Tomislav Debogovic, Ferdinando Tiezzi, Pedro Robustillo Bayon

A low-profile multi-function antenna system suitable for small satellites is presented in this paper. The antenna system operates at UHF frequency band (400 MHz) and comprises eight miniaturised radiating elements (REs) based on a folded planar inverted-F ...

On lattice codes for Gaussian interference channels

Michael Christoph Gastpar, Jingge Zhu

The usefulness of lattice codes is investigated for two-user Gaussian interference channels (IC). A coding scheme based on the compute-and-forward technique is shown to achieve the capacity region of the Gaussian IC under strong interference. The proposed ...

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 ...

Resource Allocation and Performance Analysis for Multiuser Video Transmission over Doubly Selective Channels

Laura Toni

We consider an uplink multicarrier system with multiple video users who want to send compressed video data to the base station. In the time domain, we model the time varying channel using Jakes’ model, and in the frequency domain, each subcarrier is assume ...

Reverberant Audio Source Separation via Sparse and Low-Rank Modeling

Pierre Vandergheynst

The performance of audio source separation from underde- termined convolutive mixture assuming known mixing filters can be significantly improved by using an analysis sparse prior optimized by a reweighting l1 scheme and a wideband data- fidelity term, as ...

Gaussian (dirty) multiple access channels: a compute-and-forward perspective

Michael Christoph Gastpar, Jingge Zhu

Lattice codes are applied to the two-user Gaussian multiple access channel (MAC) combined with a modified compute-and-forward transmitting scheme. It is shown that non-corner points on the boundary of the capacity region can be achieved by decoding two int ...

Frequency up-converting Vibration Energy Harvester with Multiple Impacting Beams for Enhanced Wideband Operation at Low Frequencies

Nico de Rooij, Danick Briand, Andres Felipe Vasquez Quintero, Robert Andrew Lockhart

This work presents an approach for increasing operational bandwidth of a vibration energy harvester in low-frequency environments by effectively exploiting contact-based frequency up-conversion. It was implemented by a couple of low-frequency resonators wi ...

Orthogonal multicarrier modulations in satellite uplinks

Stefano Rosati

In this paper, we analyze Orthogonal Frequency-Division Multiple Access and Single-Carrier Frequency Division Multiple Access as alternative physical layer schemes for the up-link of a satellite network. Both orthogonal frequency-division multiple access a ...

Theoretical assessment of the maximum obtainable power in wireless power transfer constrained by human body exposure limits in a typical room scenario

Valerio De Santis

In this study, the maximum received power obtainable through wireless power transfer (WPT) by a small receiver (Rx) coil from a relatively large transmitter (Tx) coil is numerically estimated in the frequency range from 100 kHz to 10 MHz based on human bod ...
