Maximum Throughput Gain of Compute-and-Forward for Multiple Unicast

Michael Christoph Gastpar, Jasper Goseling

Compute-and-Forward (CF), also known as reliable physical layer network coding, is a technique that provides the possibility of exploiting the features of broadcast and superposition in wireless networks. It has been shown that the throughput for multiple ...

Widely Tunable Picosecond-Pulsed Source near 2 μm based on Cascaded Raman Wavelength Shifting

Camille Sophie Brès, Adrien Billat, Steevy Joyce Cordette, Yu-Pei Tseng

We demonstrate a cavity-less picosecond pulsed source near 2μm, tunable over more than 200nm based on third order cascaded Raman wavelength shifting. Up to 44% conversion is achieved for 100mW peak powers at 200MHz repetition rate. ...

Differential Pulse-Width Pair Brillouin Optical Time-Domain Analysis Employing Raman Amplification and Optical Pulse Coding

Marcelo Alfonso Soto Hernandez

We report on an advanced optical fiber sensing implementation enabling submeter resolution over long distance exploiting Brillouin optical time-domain analysis with differential pulse-width pair. Long sensing distances have been attained thanks to the comb ...

Compute-and-Forward: Multiple Bi-directional Sessions on the Line Network

Michael Christoph Gastpar, Jasper Goseling

Signal superposition and broadcast are important features of the wireless medium. Compute-and-Forward, also known as Physical Layer Network Coding, is a technique exploit- ing these features in order to improve performance of wireless networks. In this pap ...

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, ...

Physical-layer Network Coding on the Random-access Channel

Michael Christoph Gastpar, Jasper Goseling

We consider a physical-layer network coding strat- egy for the random-access channel, based on compute-and- forward. When packets collide, it is possible to reliably recover a linear combination of the packets at the receiver. Over many rounds of transmiss ...

Uplink Resource Management for Multiuser OFDM Video Transmission Systems: Analysis and Algorithm Design

Laura Toni

We consider a multiuser OFDM system in which users want to transmit videos via a base station. The base station knows the channel state information (CSI) as well as the rate distortion (RD) information of the video streams and tries to allocate power and s ...

Linear Function Computation in Networks: Duality and Constant Gap Results

Michael Christoph Gastpar

In linear function computation, multiple source nodes communicate across a relay network to a single destination whose goal is to recover linear functions of the original source data. When the relay network is a linear deterministic network, a duality rela ...

Firmware for ensuring realtime radio regulations compliance in WSN

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 ...
