A Fast Interior Point Method for Atomic Norm Soft Thresholding
Thomas Lundgaard Hansen, Tobias Lindstrøm Jensen
The atomic norm provides a generalization of the -norm to continuous parameter spaces. When applied as a sparse regularizer for line spectral estimation the solution can be…
Superfast Line Spectral Estimation
Thomas Lundgaard Hansen, Bernard Henri Fleury, Bhaskar D. Rao
A number of recent works have proposed to solve the line spectral estimation problem by applying off-the-grid extensions of sparse estimation techniques. These methods are preferab…
Variational Bayesian Inference of Line Spectra
Mihai-Alin Badiu, Thomas Lundgaard Hansen, Bernard Henri Fleury
In this paper, we address the fundamental problem of line spectral estimation in a Bayesian framework. We target model order and parameter estimation via variational inference in a…
An Iterative Receiver for OFDM With Sparsity-Based Parametric Channel Estimation
Thomas L. Hansen, Peter B. Jørgensen, Mihai-Alin Badiu +1
In this work we design a receiver that iteratively passes soft information between the channel estimation and data decoding stages. The receiver incorporates sparsity-based paramet…
