POLO: Phase-Only Localization in Uplink Distributed MIMO Systems
Sauradeep Dey, Musa Furkan Keskin, Dario Tagliaferri +3
We propose a low-complexity localization framework for uplink distributed MIMO (D-MIMO) systems, targeting the challenge of minimizing the highly spiky maximum-likelihood (ML) cost…
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…
3-20 GHz Wideband Tightly-Coupled Dual-Polarized Vivaldi Antenna Array
Niko Lindvall, Mikko Heino, Mikko Valkama
Very wideband apertures are needed in positioning, sensing, spectrum monitoring, and modern spread spectrum, e.g., frequency hopping systems. Vivaldi antennas are one of the promin…
Clutter Suppression in Bistatic ISAC with Joint Angle and Doppler Estimation
M. Ertug Pihtili, Julia Equi, Ossi Kaltiokallio +4
The coexistence of radar and communications in wireless systems marks a paradigm shift for the sixth-generation (6G) networks. As 6G systems are expected to operate at higher frequ…
Meta-Learning Based Radio Frequency Fingerprinting for GNSS Spoofing Detection
Leatile Marata, Juhani Sankari, Eslam Eldeeb +2
The rapid development of technology has led to an increase in the number of devices that rely on position, velocity, and time (PVT) information to perform their functions. As such,…
UNILocPro: Unified Localization Integrating Model-Based Geometry and Channel Charting
Yuhao Zhang, Guangjin Pan, Musa Furkan Keskin +3
In this paper, we propose a unified localization framework (called UNILocPro) that integrates model-based localization and channel charting (CC) for mixed line-of-sight (LoS)/non-l…
Sensing with Mobile Devices through Radio SLAM: Models, Methods, Opportunities, and Challenges
Yu Ge, Ossi Kaltiokallio, Elizaveta Rastorgueva-Foi +7
The integration of sensing and communication (ISAC) is a cornerstone of 6G, enabling simultaneous environmental awareness and communication. This paper explores radio SLAM (simulta…
