A Wideband Doubly-Sparse Approach For MITO Sparse Filter Estimation

We propose an approach for the estimation of sparse filters from a convolutive mixture of sources, exploiting the time-domain sparsity of the mixing filters and the sparsity of the sources in the time-frequency (TF) domain. The proposed approach is based o ...

Estimating multiple filters from stereo mixtures: a double sparsity approach

Rémi Gribonval

We consider the problem of estimating multiple filters from convolutive mixtures of several unknown sources. We propose to exploit both the time-frequency (TF) sparsity of the sources and the sparsity of the mixing filters. Our framework consists of: a) a ...

Spatio-Chromatic Decorrelation by Shift-Invariant Filtering

Pascal Fua, Sabine Süsstrunk, Matthew Brown

In this paper we derive convolutional filters for colour image whitening and decorrelation. Whilst whitening can be achieved via eigendecomposition of the image patch covariance, this operation is neither efficient nor biologically plausible. Given the shi ...

Filter Learning for Linear Structure Segmentation

Pascal Fua, Engin Türetken, Vincent Lepetit, Germán González Serrano, Roberto Rigamonti

We introduce an approach to learning convolution filters whose joint output can be fed to a classifier that labels them as belonging to linear structures or not. The filters are learned using sparse synthesis techniques but we show that enforcing constrain ...

RF-MEMS switches with AlN dielectric and their applications

Mihai Adrian Ionescu, Montserrat Fernandez-Bolanos Badia

This paper reports on the potential of RF-MEMS technology based on aluminum nitride capacitive dielectric and nickelsuspended membranes to provide RF circuit functions in reconfigurable front-end radios. The RF performance of capacitive switches, distribut ...

Pulse distortion in linear slow light systems: theoretical limits and compensation strategies

Luc Thévenaz

We study analytically pulse distortion in linear slow light systems, and provide some useful limits on these devices. Additionally, we also show that the contributions of phase and amplitude broadening can be de-coupled and quantified. It is observed that ...

Kalman Filter to Measure Position and Speed of a Linear Actuator

Yves Perriard, Miroslav Markovic, Joël Maridor

This paper presents a method to dynamically filter the position and the speed of a linear actuator during its closing. A previous paper presented position detection without external sensor but, by simply deriving it, the corresponding speed was not usable ...

An Adaptive Diffusion Augmented CLMS Algorithm for Distributed Filtering of Noncircular Complex Signals

Ali H. Sayed

An adaptive diffusion augmented complex least mean square (D-ACLMS) algorithm for collaborative processing of the generality of complex signals over distributed networks is proposed. The algorithm enables the estimation of both second order circular (prope ...

Low-Power and Widely-Tunable Linearized Biquadratic Low-Pass Transconductor-C Filter

Seyed Armin Tajalli, Yusuf Leblebici

A sixth-order low-pass

g_m

-C filter with a very wide tuning range (

f_c

= 100 Hz to 10 MHz) is presented. The wide tuning range has been achieved without using switchable components or programmable building blocks. A single stage folded-cascode transcon ...

Optimal filtering of an incremental second-order MASH11 sigma-delta modulator

Maher Kayal, Sylvain Maréchal, François Krummenacher

This paper describes an optimal filter design procedure for a cascaded sigma-delta modulator, starting with a block schematic of a second-order topology and deriving step by step the optimal decoder. The presented filter enhances the resolution of the MASH ...
