A Multipurpose Testbed for Full-Duplex Wireless Communications

Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Pavle Belanovic

Unlike in the traditional half-duplex (HD) mode of transmission over a wireless link, in the full-duplex (FD) mode both terminals receive and transmit on the same frequency band, simultaneously. Hence, FD gives us up to twice the spectral efﬁciency of HD, ...

Network Coding

Mahdi Jafari Siavoshani

The demand for higher throughput and better efficiency are two important challenges for future communication networks. During the past decades, a lot of research studies have been devoted to investigating and proposing near optimal and efficient schemes an ...

Broadcasting and Multicasting Nested Message Sets

Shirin Saeedi Bidokhti

Finding theoretical limits on the performance of communication systems and designing schemes to achieve them is one of the fundamental questions in information theory. While the theory of point-to-point communication is well-investigated, most problems hav ...

Combinatorial algorithms for wireless information flow

Christina Fragouli, Javad Ebrahimi Boroojeni

long-standing open question in information theory is to characterize the unicast capacity of a wireless relay network. The difficulty arises due to the complex signal interactions induced in the network, since the wireless channel inherently broadcasts the ...

A Survey on Interference Networks: Interference Alignment and Neutralization

Michael Christoph Gastpar

In recent years, there has been rapid progress on understanding Gaussian networks with multiple unicast connections, and new coding techniques have emerged. The essence of multi-source networks is how to efficiently manage interference that arises from the ...

Network Coding: Beyond Throughput Benefits

Christina Fragouli

Network coding enables novel network functionalities and thus offers a wider canvas of choices when optimizing an information flow problem. In this paper, we examine the simplest possible information flow problem, a unicast connection, and explore what we ...

Embedded ultra-low power driver for a 7.2g helicopter and IrDA remote control

Patrick Clerc

In a previous project, a 7.2g helicopter made of carbon was designed and realized at the LAI. The goal of this project is to design and realize a tiny receiver and a remote capable of driving the helicopter from a distance of 2 to 4 meters. Challenges are ...

Information Theoretic Operating Regimes of Large Wireless Networks

Olivier Lévêque, Ayfer Özgür Aydin

In analyzing the point-to-point wireless channel, insights about two qualitatively different operating regimes --bandwidth- and power-limited-- have proven indispensable in the design of good communication schemes. In this paper, we propose a new scaling l ...

A Practical Hand-on Guide for Deploying a Large-scale Wireless Multi-hop Network

Julien Pierre Sacha Herzen, Adel Aziz

The knowledge of how to exactly deploy a wireless multi-hop network can be of interest for both researchers and engineers. Engineers may be interested in the possibility of extending the coverage area of their traditional access point and to provide ubiqui ...

On Cooperative Wireless Network Secrecy

Emre Telatar, Suhas Diggavi, Etienne Perron

Given that wireless communication occurs in a shared and inherently broadcast medium, the transmissions are vulnerable to undesired eavesdropping. This occurs even when a point-to-point communication is sought, and hence a fundamental question is whether w ...
