Learning-Based Phase Estimation for Multi-Frequency Carrier Phase Ranging under Structured Multipath Conditions
Jakub Bonczyk, Jakub Nikonowicz, Łukasz Matuszewski
Carrier-phase (CP) ranging is a key enabler of high-precision positioning in modern wireless systems. In multi-frequency OFDM-based sensing, phase observations across subcarriers p…
A Robust 5G Terrestrial Positioning System with Sensor Fusion in GNSS-denied Scenarios
Hamed Talebian, Nazrul Mohamed Nazeer, Darius Chmieliauskas +5
This paper presents a terrestrial localization system based on 5G infrastructure as a viable alternative to GNSS, particularly in scenarios where GNSS signals are obstructed or una…
Indoor Positioning in 5G-Advanced: Challenges and Solution towards Centimeter-level Accuracy with Carrier Phase Enhancements
Jakub Nikonowicz, Aamir Mahmood, Muhammad Ikram Ashraf +2
After robust connectivity, precise positioning is evolving into an innovative component of 5G service offerings for industrial use-cases and verticals with challenging indoor radio…
Sequence Alignment Algorithm for Statistical Similarity Assessment
Jakub Nikonowicz, Łukasz Matuszewski, Paweł Kubczak
This paper presents a new approach to statistical similarity assessment based on sequence alignment. The algorithm performs mutual matching of two random sequences by successively…
A Blind Signal Separation Algorithm for Energy Detection of Dynamic PU Signals
Jakub Nikonowicz, Aamir Mahmood, Mikael Gidlund
Energy detection process for enabling opportunistic spectrum access in dynamic primary user (PU) scenarios, where PU changes state from active to inactive at random time instances,…
Quantitative Benchmarks and New Directions for Noise Power Estimation Methods in ISM Radio Environment
Jakub Nikonowicz, Aamir Mahmood, Emiliano Sisinni +1
