Robustness of Covariance Estimators with Application in Activity Detection
Hendrik Bernd Zarucha, Peter Jung, Giuseppe Caire
The first part of this work considers a general class of covariance estimators. Each estimator of that class is generated by a real-valued function and a set of model covarianc…

Non-negative Sparse Recovery at Minimal Sampling Rate
Hendrik Bernd Zarucha, Peter Jung
It is known that sparse recovery is possible if the number of measurements is in the order of the sparsity, but the corresponding decoders either lack polynomial decoding time or r…
