Singer-Difference-Set Qudit Stabilizer Codes from Non-Degenerate Quadrics in PG(d,q)PG(d,q): Construction, Structural Theorems, and Monte-Carlo Performance
Michel Kulhandjian, Lajos Hanzo
We propose Q(q,d), a family of q-ary non-CSS qudit stabilizer codes with prime power q and dimension d >= 2, constructed from Singer difference sets and non-degenerate quadrics in…
An explicit half-flip family of 32-modular Hadamard matrices at L = 3 mod 8: structural placement and mod-tower analysis
Michel Kulhandjian
Motivated by Eliahou's 64-modular Hadamard construction at the smallest open Hadamard order n=668, we introduce an explicit half-flip family of 32-modular Hadamard matrices at orde…
Jamming-Resilient Sparse Delay-Doppler NOMA: Unitary Precoding, Randomized Active Sets, and Superincreasing Power Allocation
Michel Kulhandjian, Hovannes Kulhandjian, Theodoros A. Tsiftsis
We propose a sparse delay-Doppler NOMA scheme resilient to intentional jamming. The transmitter places user data on a small random subset of delay-Doppler bins, spreads the result…
The impact of mobility, beam sweeping and smart jammers on security vulnerabilities of 5G cells
Ghazal Asemian, Michel Kulhandjian, Mohammadreza Amini +3
The vulnerability of 5G networks to jamming attacks has emerged as a significant concern. This paper contributes in two primary aspects. Firstly, it investigates the effect of a mu…
AI-based Drone Assisted Human Rescue in Disaster Environments: Challenges and Opportunities
Narek Papyan, Michel Kulhandjian, Hovannes Kulhandjian +1
In this survey we are focusing on utilizing drone-based systems for the detection of individuals, particularly by identifying human screams and other distress signals. This study h…
Delay-Doppler Domain Pulse Design for OTFS-NOMA
Michel Kulhandjian, Hovannes Kulhandjian, Gunes Karabulut Kurt +1
We address the challenge of developing an orthogonal time-frequency space (OTFS)-based non-orthogonal multiple access (NOMA) system where each user is modulated using orthogonal pu…
Bypassing a Reactive Jammer via NOMA-Based Transmissions in Critical Missions
Mohammadreza Amini, Ghazal Asemian, Michel Kulhandjian +3
Wireless networks can be vulnerable to radio jamming attacks. The quality of service under a jamming attack is not guaranteed and the service requirements such as reliability, late…
Deep Dict: Deep Learning-based Lossy Time Series Compressor for IoT Data
Jinxin Liu, Petar Djukic, Michel Kulhandjian +1
We propose Deep Dict, a deep learning-based lossy time series compressor designed to achieve a high compression ratio while maintaining decompression error within a predefined rang…
On the Impact of CDL and TDL Augmentation for RF Fingerprinting under Impaired Channels
Omer Melih Gul, Michel Kulhandjian, Burak Kantarci +3
Cyber-physical systems have recently been used in several areas (such as connected and autonomous vehicles) due to their high maneuverability. On the other hand, they are susceptib…
Low-Density Spreading Design Based on an Algebraic Scheme for NOMA Systems
Goldwyn Millar, Michel Kulhandjian, Ayse Alaca +3
NOMA) technique based on an algebraic design is studied. We propose an improved low-density spreading (LDS) sequence design based on projective geometry. In terms of its bit error…
