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…
Fundamentals of LEO Based Localization
Don-Roberts Emenonye, Harpreet S. Dhillon, R. Michael Buehrer
In this paper, we derive the fundamental limits of low earth orbit (LEO) enabled localization by analyzing the available information in signals from multiple LEOs during different…
Diffraction Aided Wireless Positioning
Gaurav Duggal, R. Michael Buehrer, Harpreet S. Dhillon +1
Wireless positioning in Non-Line-of-Sight (NLoS) scenarios presents significant challenges due to multipath effects that lead to biased measurements and reduced positioning accurac…
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…
3D Positioning using a New Diffraction Path Model
Gaurav Duggal, R. Michael Buehrer, Harpreet S. Dhillon +1
Enhancing 3D and Z-axis positioning accuracy is crucial for effective rescue in indoor emergencies, ensuring safety for emergency responders and at-risk individuals. Additionally,…
Peak Age of Information under Tandem of Queues
Ashirwad Sinha, Shubhransh Singhvi, Praful D. Mankar +1
This paper considers a communication system where a source sends time-sensitive information to its destination via queues in tandem. We assume that the arrival process as well as t…
Characterization of Capacity and Outage of RIS-aided Downlink Systems under Rician Fading
Kali Krishna Kota, Praful D. Mankar, Harpreet S. Dhillon
This letter presents optimal beamforming and outage analysis for a Reconfigurable Intelligent Surface (RIS)-aided multiple input single output downlink system under Rician fading o…
Capacity Maximization for RIS-assisted Multi-user MISO Communication Systems
M. S. S. Manasa, Kali Krishna Kota, Praful D. Mankar +1
We consider a multi-user multiple input single output (MU-MISO) system assisted by a reconfigurable intelligent surface (RIS). For such a system, we aim to optimally select the RIS…
