RadioRange: An Open-Source Digital Twin-based Ranging Simulator for UWB, Wi-Fi, and 5G
Zhen Lyu, Yidi Chen, Li-Ta Hsu +1
Accurate RF-based ranging is critical for location-aware wireless systems, yet no open platform exists for fair, reproducible comparison across protocols under realistic hardware i…
Logistic-aided Huber M-estimator for robust GNSS positioning
Zhengdao Li, Penggao Yan, Li-Ta Hsu
This paper develops a logistic-aided Huber (LAH) M-estimator for robust GNSS positioning under long-tailed, multipath-affected measurement errors. The key idea is to leverage a log…
MIMO OFDM-Enabled ISAC for Low-Altitude Non-Cooperative UAV Surveillance: A Survey
Shiyu Bai, Sijia Li, Cunyi Yin +4
The widespread use of unmanned aerial vehicles (UAVs) in low-altitude airspace has raised significant safety and security concerns, motivating the development of reliable non-coope…
Certifiably Optimal Doppler Positioning using Opportunistic LEO Satellites
Baoshan Song, Weisong Wen, Qi Zhang +2
To provide backup and augmentation to global navigation satellite system (GNSS), Doppler shift from Low Earth Orbit (LEO) satellites can be employed as signals of opportunity (SOP)…
