A New Location Estimator for Mixed LOS & NLOS scenarios
Gaurav Duggal, Richard M. Buehrer, Harpreet S. Dhillon +1
Time-of-arrival (TOA)-based localization in mixed line-of-sight (LOS) and non-line-of-sight (NLOS) environments is challenging because conventional Euclidean range models do not ca…
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…
Indoor Positioning for Public Safety: Role of UAVs, LEOs, and Propagation-Aware Techniques
Gaurav Duggal, Harish K. Dureppagari, Harpreet S. Dhillon +2
Effective indoor positioning is critical for public safety, enabling first responders to locate at-risk individuals accurately during emergency scenarios. However, traditional Glob…
Impact of Frequency on Diffraction-Aided Wireless Positioning
Gaurav Duggal, Anand M. Kumar, R. Michael Buehrer +3
This paper tackles the challenge of accurate positioning in Non-Line-of-Sight (NLoS) environments, with a focus on indoor public safety scenarios where NLoS bias severely impacts l…
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…
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,…
Line-of-Sight Probability for Outdoor-to-Indoor UAV-Assisted Emergency Networks
Gaurav Duggal, R. Michael Buehrer, Nishith Tripathi +1
For emergency response scenarios like firefighting in urban environments, there is a need to both localize emergency responders inside the building and also support a high bandwidt…
Doppler-Resilient 802.11ad-Based Ultra-Short Range Automotive Joint Radar-Communications System
Gaurav Duggal, Shelly Vishwakarma, Kumar Vijay Mishra +1
We present an ultra-short range IEEE 802.11ad-based automotive joint radar-communications (JRC) framework, wherein we improve the radar's Doppler resilience by incorporating Prouhe…
