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…
A Comprehensive Survey of Mamba Architectures for Medical Image Analysis: Classification, Segmentation, Restoration and Beyond
Shubhi Bansal, Sreeharish A, Madhava Prasath J +6
Mamba, a special case of the State Space Model, is gaining popularity as an alternative to template-based deep learning approaches in medical image analysis. While transformers are…
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…
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…
