On Degraded Two Message Set Broadcast

Christina Fragouli, Suhas Diggavi, Vinod Malathidevi Prabhakaran, Shirin Saeedi Bidokhti

We consider the two message set problem, where a source broadcasts a common message

W_1

to an arbitrary set of receivers

\mathcal{U}

and a private message

W_2

to a subset of the receivers

\mathcal{P}\subseteq \mathcal{U}

. Transmissions occur over l ...

Performance Comparison of UWB Impulse-Based Multiple Access Schemes in Indoor Multipath Channels

Pierre-André Farine, Cyril Botteron, Paul Saad

In this paper, we consider an impulse-based ultrawideband (UWB) receiver and assess the performance of different multiple access and modulation schemes, including time-hopping pulse position modulation (TH-PPM), time-hopping binary phase shift keying (TH-B ...

Arbitrarily dirty paper coding and applications

Michael Christoph Gastpar

A deterministic dirty-paper coding strategy for communication over an arbitrarily varying channel with an interference signal known to the transmitter is investigated. The presence of a known interference signal at the transmitter is shown to provide some ...

Performance of an Impulse Radio Communication System in the Presence of Gaussian Jitter

Pierre-André Farine, Cyril Botteron

In this paper, the bit error rate (BER) performance for an ultra-wide bandwidth (UWB) impulse radio in an additive white Gaussian noise (AWGN) transmission channel and with Gaussian jitter is estimated. The assumed receiver combines the received pulses to ...

On the concentration of the capacity for a code division multiple access system

Nicolas Macris, Satish Babu Korada

We prove the concentration of the capacity, in the large system limit, for a code division multiple access system over an additive white Gaussian noise channel, with Gaussian signature sequences and {\it binary input} symbols. The probabilistic tools that ...

Even Small Birds are Unique: Population Protocols with Identifiers

Rachid Guerraoui, Eric Ruppert

Although much research has been devoted to designing and experimenting on ad hoc networks of tiny devices, very little has focussed on devising theoretical models to capture the inherent power and limitations of such networks. A notable exception is the po ...

Unsupervised Spectral Subtraction for Noise-Robust ASR on Unknown Transmission Channels

Hervé Bourlard, Guillaume Lathoud

This paper addresses several issues of classical spectral subtraction methods with respect to the automatic speech recognition task in noisy environments. The main contributions of this paper are twofold. First, a channel normalization method is proposed t ...

Randomization bounds on Gaussian arbitrarily varying channels

Michael Christoph Gastpar

The random coding capacity of the Gaussian arbitrarily varying channel (GAVC) under a maximal probability of error criterion is equal to that of an additive white Gaussian noise (AWGN) channel with the interference power as additional noise. The determinis ...

Rayleigh Fading Multiple Access Channel without Channel State Information

Ninoslav Marina

In this paper we determine bounds of the capacity region of a two-user multiple-access channel with Rayleigh fading when neither the transmitters nor the receiver has channel state information (CSI). We assume that the fading coefficients as well as the ad ...
