Periodic OFDMA: A Low-PAPR Multiple Access Scheme for Uplink Communications in 5G and Beyond
Gokce Hacioglu, Serkan Vela
Multiple access techniques are vital for 5G and beyond. While Orthogonal Frequency Division Multiple Access (OFDMA) is standard, its high peak-to-average power ratio (PAPR) reduces…
Filterless Multi-Color VLC via DC-Biased QCT
Idris Cinemre, Serkan Vela, Gokce Hacioglu
Multi-color visible light communication (VLC) can increase throughput and enable joint lighting and communication operation, but practical color-based schemes such as color shift k…
NOMA-CSK Integrated VLC System with Reinforcement Learning-Based Multi-Objective Power Allocation
Serkan Vela, Gokce Hacioglu
This paper introduces a novel framework that synergistically combines Non-Orthogonal Multiple Access (NOMA) with Color Shift Keying (CSK) modulation to substantially boost spectral…
Physical Layer Authentication With Colored RIS in Visible Light Communications
Besra Cetindere Vela, Serkan Vela, Stefano Tomasin
We study a visible light communication (VLC) system that employs a colored reconfigurable intelligent surface (CRIS) based on dichroic mirrors that reflect light at tunable frequen…
