Fourier Preconditioning for Neural Feature Learning
Preston Pitzer, Anish Pradhan, Harpreet S. Dhillon
Mutual information (MI)-inspired feature learning techniques are capable of generating low-dimensional embeddings that retain nonlinear dependence structures, but direct estimation…
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…
Mutual Information-Driven Visualization and Clustering for Core KPI Selection in O-RAN Testing
Anish Pradhan, Lingjia Liu, Harpreet S. Dhillon
O-RAN testing is becoming increasingly difficult with the exponentially growing number of performance measurements as the system grows more complex, with additional units, interfac…
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…
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…
