Cooperative strategies and capacity theorems for relay networks

Michael Christoph Gastpar

Coding strategies that exploit node cooperation are developed for relay networks. Two basic schemes are studied: the relays decode-and-forward the source message to the destination, or they compress-and-forward their channel outputs to the destination. The ...

Joint source-channel coding with feedback

Communications is about conveying information from one point to another subject to certain performance constraints. The information is assumed to be generated by a source and may, for example, represent a voice waveform, the reading of a thermal sensor, or ...

Algebraic methods for channel coding

Frédérique Oggier

This work is dedicated to developing algebraic methods for channel coding. Its goal is to show that in different contexts, namely single-antenna Rayleigh fading channels, coherent and non-coherent MIMO channels, algebraic techniques can provide useful tool ...

Unequal Error Protection of Atomic Image Streams

Pascal Frossard, Pierre Vandergheynst

This paper presents an unequal error protection scheme for atomic image bitstreams. An atomic stream is the encoded version of a digital image, which is represented as a sum of bi-dimensional functions, as typically generated by Matching Pursuit encoders. ...

Effect of Interfering Users on the Modulation Order and Code Rate for UWB Impulse-Radio Bit-Interleaved Coded M-ary PPM

Jean-Yves Le Boudec, Ruben Merz

We consider the impact of multi-user interference on a bit-interleaved coded-modulation system with M-ary PPM (BIC M-ary PPM) in an impulse-radio ultra-wideband physical layer. In a realistic scenario such as an ad hoc network, the interference is inherent ...

MIMO OFDM receivers for Systems with IQ imbalances

Ali H. Sayed

Orthogonal frequency division multiplexing (OFDM) is a widely recognized modulation scheme for high data rate communications. However, the implementation of OFDM-based systems suffers from in-phase and quadrature-phase (IQ) imbalances in the front-end anal ...

FPGA implementation of Viterbi decoders for MIMO-BICM

Andreas Peter Burg

The FPGA implementation of Viterbi decoders for multiple-input multiple-output (MIMO) wireless communication systems with bit-interleaved coded modulation (BICM) and perantenna coding is considered. The paper describes how the recursive add-compare-select ...

Power, Spatio-Temporal Bandwidth, and Distortion in Large Sensor Networks

Martin Vetterli, Michael Christoph Gastpar

For a class of sensor networks, the task is to monitor an underlying physical phenomenon over space and time through an imperfect observation process. The sensors can communicate back to a central data collector over a noisy channel. The key pa- rameters i ...
