OMP-type Algorithm with Structured Sparsity Patterns for Multipath Radar Signals
Tabea Rebafka, Céline Lévy-Leduc, Maurice Charbit
A transmitted, unknown radar signal is observed at the receiver through more than one path in additive noise. The aim is to recover the waveform of the intercepted signal and to si…

Central limit theorem for the robust log-regression wavelet estimation of the memory parameter in the Gaussian semi-parametric context
Olaf Kouamo, Céline Lévy-Leduc, Eric Moulines
In this paper, we study robust estimators of the memory parameter d of a (possibly) non stationary Gaussian time series with generalized spectral density f. This generalized spectr…
