Low-Complexity Multi-User Non-Line-of-Sight Channel Estimation
Mohammad Abu Aqoulah, Doğa Gürgünoğlu, Gábor Fodor +1
Future radio access networks are expected to rely on large-aperture antenna arrays, for which an increasing portion of the coverage region may fall within the radiative near-field.…
Dual-Satellite Doppler Accuracy Prediction and Geometry Selection for Sparse LEO Signals of Opportunity
Qi Liu, Marc Fernández-Temprado, Antoni Reus-Bergas +4
Low Earth Orbit (LEO) satellites have emerged as a promising complement to GNSS for positioning in signal challenged environments. In sparse LEO signals of opportunity scenarios, D…
Geometric Performance Analysis of Doppler-Based Positioning with a Single LEO Satellite
Qi Liu, Marc Fernandez-Temprado, Antoni Reus-Bergas +2
Low Earth Orbit (LEO) satellites have gained increasing attention as potential signal sources for Positioning, Navigation and Timing (PNT) applications. However, while most existin…
Theoretical and Experimental Evaluation of AoA Estimation in Single-Anchor 5G Uplink Positioning
Thodoris Spanos, Fran Fabra, José A. López-Salcedo +4
As we move towards 6G, the demand for high-precision, cost-effective positioning solutions becomes increasingly critical. Single-anchor positioning offers a promising alternative t…
Angle of Arrival Estimation Using SRS in 5G NR Uplink Scenarios
Thodoris Spanos, Fran Fabra, José A. López-Salcedo +4
This paper presents a comprehensive exploration of Angle of Arrival (AoA) estimation techniques in 5G environments, using the Sounding Reference Signal (SRS) in Uplink scenarios bo…
USRP-Based Single Anchor Positioning: AoA with 5G Uplink Signals, and UWB Ranging
Thodoris Spanos, Fran Fabra, José A. López-Salcedo +4
This paper presents a novel testbed designed for 5th-Generation (5G) positioning using Universal Software Radio Peripherals (USRPs). The testbed integrates multiple units: an Opera…
