Identification of multi-input systems: variance analysis and input design issues

Dominique Bonvin, Alireza Karimi, Ljubisa Miskovic

This paper examines the identification of multi-input systems. Motivated by an experiment design problem (should one excite the various inputs simultaneously or separately), we examine the effect of an additional input on the variance of the estimated coef ...

On noisy feedback for interference channels

Michael Christoph Gastpar

An upper bound is established on the usefulness of noisy feedback for the interference channel (IC). The bound is based on the Hekstra-Willems dependence-balance arguments for two-way channels. For Gaussian ICs, the results suggest that feedback loses its ...

Harmonic Plus Noise Model for Concatenative Speech Synthesis

This project develops the new model Harmonic Plus Noise applied for the concatenative speech synthesis. The software is composed of an analysis part (off-line process) applied on the first initial database and a synthesis part (real time process) applied o ...

Power spectra of random spike fields and related processes

Andrea Ridolfi, Pierre Bremaud

This article reviews known results and contains new ones concerning the power spectra of large classes of signals and random fields driven by an underlying point process, such as spatial shot noises (with random impulse response and arbitrary basic station ...

Multiresolution Motion Estimation for Omnidirectional Images

Pascal Frossard, Pierre Vandergheynst, Ivana Tosic, Iva Bogdanova Vandergheynst

This paper presents a novel local motion estimation algorithm for omnidirectional images. The algorithm captures correlation between two spherical images of a scene, taken from arbitrary viewpoints, with the objective to reduce the encoding rate of these i ...

UWB Signals as Shot Noises

Andrea Ridolfi

We present a shot-noise based model for a large family of ultrawide bandwidth (UWB) signals. These include time-hopping and direct-sequence signaling with pulse position, interval and amplitude modulations. Each specific signal is constructed by adding fea ...

Motion likelihood and proposal modeling in Model-Based Stochastic Tracking

Daniel Gatica-Perez, Jean-Marc Odobez

Particle filtering is now established as one of the most popular methods for visual tracking. Within this framework, there are two important considerations. The first one refers to the generic assumption that the observations are temporally independent giv ...

Acoustic Echo Cancellation for Human-Robot Communications

Jérôme Berclaz

This master thesis presents a new efficient method of acoustic echo cancellation targeted at speech recognition for robots. The proposed algorithm features a new double-talk detector, an enhanced initialization and a new noise estimation method. The DTD al ...

Chromatic contrast detection in spatial chromatic noise

Sabine Süsstrunk, Gianluca Monaci, Gloria Menegaz

The spectral properties of chromatic detection mechanisms were investigated using a noise-masking paradigm. Contrast detection thresholds were measured for a signal with a Gaussian spatial profile, modulated in the equiluminant plane in the presence of spa ...
