Direction of arrival estimation using robust complex Lasso
Esa Ollila
The Lasso (Least Absolute Shrinkage and Selection Operator) has been a popular technique for simultaneous linear regression estimation and variable selection. In this paper, we pro…
Multichannel sparse recovery of complex-valued signals using Huber's criterion
Esa Ollila
In this paper, we generalize Huber's criterion to multichannel sparse recovery problem of complex-valued measurements where the objective is to find good recovery of jointly sparse…
Nonparametric Simultaneous Sparse Recovery: an Application to Source Localization
Esa Ollila
We consider multichannel sparse recovery problem where the objective is to find good recovery of jointly sparse unknown signal vectors from the given multiple measurement vectors w…
On asymptotics of ICA estimators and their performance indices
Pauliina Ilmonen, Klaus Nordhausen, Hannu Oja +1
Independent component analysis (ICA) has become a popular multivariate analysis and signal processing technique with diverse applications. This paper is targeted at discussing theo…
