Exploiting Double-Bounce Paths in Snapshot Radio SLAM: Bounds, Algorithms and Experiments
Xi Zhang, Yu Ge, Ossi Kaltiokallio +3
Radio-based simultaneous localization and mapping (SLAM) has the potential to provide precise user equipment (UE) localization and environmental sensing capabilities by exploiting…
Phase-Only Positioning in Distributed MIMO Under Phase Impairments: AP Selection Using Deep Learning
Fatih Ayten, Musa Furkan Keskin, Akshay Jain +5
Carrier phase positioning (CPP) can enable cm-level accuracy in next-generation wireless systems, while recent literature shows that accuracy remains high using phase-only measurem…
Multi-band Carrier Phase Positioning toward 6G: Performance Bounds and Efficient Estimators
Ehsan Shourezari, Ossi Kaltiokallio, Mehmet C. Ilter +4
In addition to satellite systems, carrier phase positioning (CPP) is gaining attraction also in terrestrial mobile networks, particularly in 5G New Radio evolution toward 6G. One k…
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…
