Atomic Hybrid Sparse/Diffuse Channel Estimation and Cramér-Rao Bounds Analysis
Lei Lyu, Maxime Ferreira Da Costa, Urbashi Mitra
In this paper, an atomic hybrid sparse/diffuse (aHSD) channel model in the frequency domain is proposed. Based on a structural analysis of the resolvable paths and diffuse scatteri…

Guaranteed Private Communication with Secret Block Structure
Maxime Ferreira Da Costa, Jianxiu Li, Urbashi Mitra
A novel private communication framework is proposed where privacy is induced by transmitting over a channel instances of linear inverse problems that are identifiable to the legiti…
