Hybrid Atomic Norm Sparse/Diffuse Channel Estimation
Lei Lyu, Urbashi Mitra
In this paper, the hybrid sparse/diffuse (HSD) channel model in frequency domain is proposed. Based on the structural analysis on the resolvable paths and diffuse scattering statis…
Causal Link Discovery with Unequal Edge Error Tolerance
Joni Shaska, Urbashi Mitra
This paper proposes a novel framework for causal discovery with asymmetric error control, called Neyman-Pearson causal discovery. Despite the importance of applications where diffe…
Delay-Angle Information Spoofing for Channel State Information-Free Location-Privacy Enhancement
Jianxiu Li, Urbashi Mitra
In this paper, a delay-angle information spoofing (DAIS) strategy is proposed to enhance the location privacy at the physical layer. More precisely, the location-relevant delays an…
Optimized Parameter Design for Channel State Information-Free Location Spoofing
Jianxiu Li, Urbashi Mitra
In this paper, an augmented analysis of a delay-angle information spoofing (DAIS) is provided for location-privacy preservation, where the location-relevant delays and angles are a…
Channel State Information-Free Location-Privacy Enhancement: Delay-Angle Information Spoofing
Jianxiu Li, Urbashi Mitra
In this paper, a delay-angle information spoofing (DAIS) strategy is proposed for location-privacy enhancement. By shifting the location-relevant delays and angles without the aid…
