Optimal Anchor Placement for Wireless Localization in Mixed LOS and NLOS Scenarios
Gaurav Duggal, R. Michael Buehrer, Harpreet S. Dhillon +1
This paper develops a general optimal experimental design framework for anchor placement in localization and related estimation problems whose Fisher information matrix (FIM) can b…
Björck Sequences: Extension to Arbitrary Lengths, Correlation Analysis, and Applications to Wireless Systems
Harish K. Dureppagari, Chiranjib Saha, R. Michael Buehrer +1
In this paper, we propose a sequence construction framework that extends prime-length Björck sequences, a class of Constant Amplitude Zero Autocorrelation (CAZAC) sequences, to arb…
Experimental Validation of a 3GPP Compliant 5G-Based Positioning System
Sarik Dhungel, Gaurav Duggal, Dara Ron +4
The advent of 5G positioning techniques by 3GPP has unlocked possibilities for applications in public safety, vehicular systems, and location-based services. However, these applica…
LEO-based Positioning: Foundations, Signal Design, and Receiver Enhancements for 6G NTN
Harish K. Dureppagari, Chiranjib Saha, Harikumar Krishnamurthy +4
The integration of non-terrestrial networks (NTN) into 5G new radio (NR) has opened up the possibility of developing a new positioning infrastructure using NR signals from Low-Eart…
Foundations of Vision-Based Localization: A New Approach to Localizability Analysis Using Stochastic Geometry
Haozhou Hu, Harpreet S. Dhillon, R. Michael Buehrer
Despite significant algorithmic advances in vision-based positioning, a comprehensive probabilistic framework to study its performance has remained unexplored. The main objective o…
Joint 9D Receiver Localization and Ephemeris Correction with LEO and G Base Stations
Don-Roberts Emenonye, Wasif J. Hussain, Harpreet S. Dhillon +1
This paper leverages Fisher information to examine the interaction between low-Earth orbit (LEO) satellites and 5G base stations (BSs) in enabling 9D receiver localization and refi…
