Ambient IoT Backscatter Devices as Passive Anchors for NLOS Cellular Positioning: Fundamental Limits
Hüseyin YiÄitler, Musa Furkan Keskin, Ossi Kaltiokallio +1
The paper studies how ambient IoT backscatter devices placed at known locations can act as low‑cost passive anchors to improve non‑line‑of‑sight cellular positioning, and derives f…
Gaussian Process-Based Extended Object Estimation for 6G ISAC at Millimeter-Wave Frequencies
M. Ertug Pihtili, Ossi Kaltiokallio, Julia Equi +4
This paper introduces a Gaussian process (GP)-based method for extended object estimation (EOE) in integrated sensing and communication (ISAC) scenarios, representing a promising a…
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…
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…
