Fractional Doppler Effects on OTFS-NOMA HetNets with Mixed-Mobility Users
Wafa Hedhly, Leila Musavian, Nikolaos Thomos
The paper examines how fractional Doppler causes inter‑Doppler interference in OTFS‑NOMA heterogeneous networks with mixed‑mobility users and shows that optimizing NOMA power alloc…
Adaptive Wavelet Division Multiplexing for Heterogeneous Mobility Users
Seyyed Erfan Fatemi, Wafa Hedhly, Leila Musavian +1
This paper proposes an adaptive wavelet division multiplexing scheme for wireless systems serving users with heterogeneous mobility profiles over frequency-selective Rayleigh fadin…
RSMA-Assisted OFDM-OTFS Hybrid Framework for Mixed-Mobility Multiuser Systems
Wafa Hedhly, Leila Musavian, Nikolaos Thomos
In future 6G vehicular networks, users employing orthogonal frequency division multiplexing (OFDM) and orthogonal time frequency space (OTFS) waveforms may coexist under diverse mo…
Constructing Composite Features for Interpretable Music-Tagging
Chenhao Xue, Weitao Hu, Joyraj Chakraborty +5
Combining multiple audio features can improve the performance of music tagging, but common deep learning-based feature fusion methods often lack interpretability. To address this p…
Performance Analysis of OTFS-NOMA System with Fractional Doppler
Wafa Hedhly, Leila Musavian, Nikolaos Thomos
In this work, we investigate the effect of fractional Doppler on the performance of a system using orthogonal time frequency space (OTFS) modulation and non-orthogonal multiple acc…
