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…
Determinantal Learning for Subset Selection in Wireless Networks
Xiangliu Tu, Chiranjib Saha, Harpreet S. Dhillon
Subset selection is central to many wireless communication problems, including link scheduling, power allocation, and spectrum management. However, these problems are often NP-comp…
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…
Deterministic and Statistical Analysis of the DoF of Continuous Linear Arrays in the Near Field
Athanasios G. Kanatas, Harris K. Armeniakos, Harpreet S. Dhillon +1
This paper examines the number of communication modes, that is, the degrees of freedom (DoF) in a wireless line-of-sight channel comprising a small continuous linear intelligent an…
Geolocation with Large LEO Constellations: Insights from Fisher Information
Don-Roberts Emenonye, Harpreet S. Dhillon, R. Michael Buehrer
Interest in the use of the low earth orbit (LEO) in space - from to - has skyrocketed; this is evident by the fact that National Aeronautics and…
Impact of Model Mismatch on DOA Estimation with MUSIC: Near-Field and Far-Field
Don-Roberts Emenonye, Harpreet S. Dhillon, R. Michael Buehrer
There has been substantial work on developing variants of the multiple signal classification (MUSIC) algorithms that take advantage of the information present in the near-field pro…
A New Statistical Approach to the Performance Analysis of Vision-based Localization
Haozhou Hu, Harpreet S. Dhillon, R. Michael Buehrer
Many modern wireless devices with accurate positioning needs also have access to vision sensors, such as a camera, radar, and Light Detection and Ranging (LiDAR). In scenarios wher…
