Robust Semiparametric DOA Estimation in non-Gaussian Environment
Stefano Fortunati, Alexandre Renaux, Frédéric Pascal
A general non-Gaussian semiparametric model is adopted to characterize the measurement vectors, i.e.\ the \textit{snapshots}, collected by a linear array. Moreover, the recently de…
Properties of a new -estimator of shape matrices
Stefano Fortunati, Alexandre Renaux, Frédéric Pascal
This paper aims at presenting a simulative analysis of the main properties of a new -estimator of shape matrices in Complex Elliptically Symmetric (CES) distributed observations…
Robust Semiparametric Efficient Estimators in Elliptical Distributions
Stefano Fortunati, Alexandre Renaux, Frédéric Pascal
Covariance matrices play a major role in statistics, signal processing and machine learning applications. This paper focuses on the \textit{semiparametric} covariance/scatter matri…
