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 ar…
LEO-based Carrier-Phase Positioning for 6G: Design Insights and Comparison with GNSS
Harish K. Dureppagari, Harikumar Krishnamurthy, Chiranjib Saha +4
The integration of non-terrestrial networks (NTN) into 5G new radio (NR) enables a new class of positioning capabilities based on cellular signals transmitted by Low-Earth Orbit (L…
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…
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…
Optimal No-Fly Zone Design for the Coexistence of Drone and Satellite Networks
Xiangliu Tu, Chiranjib Saha, Harpreet S. Dhillon
Constructing a no-fly zone (NFZ) is a straightforward and effective way to facilitate the coexistence of unmanned aerial vehicles (drones) and existing systems (typically satellite…
