Probe measurements of plasma potential nonuniformity due to edge asymmetry in large-area radio-frequency reactors: the telegraph effect

Christoph Hollenstein, Alan Howling, Laurent Fabien Hubert Sansonnens, Hannes Schmidt, Lukas Derendinger

In large-area radio-frequency (rf) capacitive reactors, the redistribution of rf current to maintain current continuity near asymmetric sidewalls causes a perturbation in rf plasma potential to propagate along the resistive plasma between capacitive sheath ...

Mean-square performance of adaptive filters using averaging theory

Ali H. Sayed

This paper uses averaging analysis to study the mean-square performance of adaptive filters, not only in terms of stability conditions but also in terms of expressions for the mean-square error and the mean-square deviation of the filters, as well as in te ...

Training-Based Channel Estimation for Multiple Antenna Broadband Transmissions

Christina Fragouli

This paper addresses the problem of training sequence design for multiple-antenna transmissions over quasi-static frequency-selective channels. To achieve the channel estimation minimum mean square error, the training sequences transmitted from the multipl ...

Reduced-Complexity Training Schemes for Multiple-Antenna Broadband Transmissions

Christina Fragouli

This paper addresses the problem of training sequence design for multiple-antenna transmissions over quasi-static frequency-selective channels. As performance metric for channel estimation, mean square error is adopted. To achieve the minimum mean square e ...

Multigrid Image Reconstruction from Arbitrarily Spaced Samples

Michaël Unser, Michael Sühling, Muthuvel Arigovindan

We propose a novel multiresolution-multigrid based signal reconstruction method from arbitrarily spaced samples. The signal is reconstructed on a uniform grid using B-splines basis functions. The computation of spline weights is formulated as a variational ...

Rate Distortion Behavior of Sparse Sources

Martin Vetterli

This paper studies the rate distortion behavior of sparse memoryless sources that serve as models of sparse signal representations. For the Hamming distortion criterion,

R(D)

is shown to be essentially linear. For the mean squared error measure, two mode ...

The prediction of speed and incline in outdoor running in humans using accelerometry

Kamiar Aminian, Yves Schutz

Purpose: To explore whether triaxial accelerometric measurements can be utilized to accurately assess speed and incline of running in free-living conditions. Methods: Body accelerations during running were recorded at the lower back and at the heel by a po ...

Tracking analysis of the LMF and LMMN adaptive algorithms

Ali H. Sayed

Although the least mean fourth (LMF) and the least mean mixed norm (LMMN) adaptive algorithms are recommended for highly nonstationary environments, their tracking capabilities are not yet fully understood. This is mainly due to the fact that both algorith ...
