Hybrid Monostatic and Bistatic Sensing for Target Localization in OFDM Systems under Phase Noise
Lucía Pallarés Rodríguez, Musa Furkan Keskin, Alireza Pourafzal +3
In hybrid monostatic-bistatic orthogonal frequency-division multiplexing (OFDM) sensing, each sensing node receives a superposition of monostatic and bistatic target returns, whose…
Radio Imaging and Resource Allocation in Frugal Multistatic D-MIMO ISAC Systems
Sauradeep Dey, Musa Furkan Keskin, Dario Tagliaferri +2
Emerging integrated sensing and communication (ISAC) systems based on distributed MIMO (D-MIMO) enable radio imaging by exploiting spatial diversity across multiple access points (…
Coordination of Ground-to-Space Reference Networks for High-Precision GNSS
Xue Xian Zheng, Xing Liu, José A. López-Salcedo +2
High-precision Global Navigation Satellite System (GNSS) services rely on accurate orbit, clock, atmospheric, and hardware-bias corrections generated from reference observations. T…
Differential LEO Navigation under Asynchronous Satellite Clocks: Architecture and Performance Bounds
Qamar Bader, Sharief Saleh, Henk Wymeersch +2
Low Earth Orbit (LEO) communication satellites have emerged as a promising source of signals of opportunity for resilient positioning, navigation, and timing (PNT) in GNSS-challeng…
From Pilot to Precoding Design: Blind Angular Spoofing For Location Privacy in MIMO Systems
Priyanka Maity, Lorenzo Italiano, Alireza Pourafzal +4
This paper studies location privacy in uplink MIMO systems, where a user equipment seeks to spoof the angular signature observed by a single base station performing localization. W…
Optimal Placement of Movable Antennas for Angle-of-Departure Estimation Under User Location Uncertainty
Lucía Pallarés-Rodríguez, Angelo Coluccia, Alessio Fascista +4
Movable antennas (MA) have gained significant attention in recent years to overcome the limitations of extremely large antenna arrays in terms of cost and power consumption. In thi…
LEO Constellations as a Decentralized GNSS Network: Optimizing PNT Corrections in Space
Xing Liu, Xue Xian Zheng, José A. López-Salcedo +2
With the rapid expansion of low Earth orbit (LEO) constellations, thousands of satellites are now in operation, many equipped with onboard GNSS receivers capable of continuous orbi…
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…
