Unified Evaluation Methodology for AI-Native Integrated Sensing and Communication
Filip Lemic, Andra Blaga, Francesco Devoti +24
The paper proposes a unified architecture and evaluation methodology for AI‑native integrated sensing and communication (ISAC) systems, including a three‑stage validation pipeline…
Sparse Sensor Arrays for Active Sensing: Models, Configurations and Applications
Robin Rajamäki, Visa Koivunen
This chapter focuses on active sensing using sparse arrays. In active sensing applications, such as radar, sonar, wireless communications, and medical ultrasound, a collection of s…
DoA Estimation with Sparse Arrays: Effects of Antenna Element Patterns and Nonidealities
Niko Lindvall, Mikko Heino, Robin Rajamäki +2
This paper studies the effects of directional antenna element complex gain patterns and nonidealities in direction of arrival (DoA) estimation. We compare sparse arrays and classic…
Beyond-Diagonal RIS: Adversarial Channels and Optimality of Low-Complexity Architectures
Atso Iivanainen, Robin Rajamäki, Visa Koivunen
Beyond-diagonal reconfigurable intelligent surfaces (BD-RISs) have recently gained attention as an enhancement to conventional RISs. BD-RISs allow optimizing not only the phase, bu…
The Adaptive -Lasso: Robustness and Oracle Properties
Emadaldin Mozafari-Majd, Visa Koivunen
This paper introduces a new regularized version of the robust -regression estimator for analyzing high-dimensional datasets subject to gross contamination in the response varia…
Quickest Change Detection for Multiple Data Streams Using the James-Stein Estimator
Topi Halme, Venugopal V. Veeravalli, Visa Koivunen
The problem of quickest change detection is studied in the context of detecting an arbitrary unknown mean-shift in multiple independent Gaussian data streams. The James-Stein estim…
