Uncertainty Principles in Risk-Aware Statistical Estimation
Nikolas P. Koumpis, Dionysios S. Kalogerias
We present a new uncertainty principle for risk-aware statistical estimation, effectively quantifying the inherent trade-off between mean squared error ($\mse$) and risk, the latte…
Matrix Completion in Colocated MIMO Radar: Recoverability, Bounds & Theoretical Guarantees
Dionysios S. Kalogerias, Athina P. Petropulu
It was recently shown that low rank matrix completion theory can be employed for designing new sampling schemes in the context of MIMO radars, which can lead to the reduction of th…
Mobile Jammers for Secrecy Rate Maximization in Cooperative Networks
Dionysios S. Kalogerias, Nikolaos Chatzipanagiotis, Michael M. Zavlanos +1
We consider a source (Alice) trying to communicate with a destination (Bob), in a way that an unauthorized node (Eve) cannot infer, based on her observations, the information that…
On the Coherence Properties of Random Euclidean Distance Matrices
Dionysios S. Kalogerias, Athina P. Petropulu
In the present paper we focus on the coherence properties of general random Euclidean distance matrices, which are very closely related to the respective matrix completion problem.…
