Transceiver-Integrated BD-RIS: Wave-Domain Signal Processing for Sustainable and Inclusive 6G
Mahmoud Raeisi, Ayoub Ammar Boudjelal, Henk Wymeersch +2
The shift toward sixth-generation (6G) wireless communications demands transceiver architectures that simultaneously support high-data-rate communications, pervasive sensing, and s…
Chirp-Based Multi-Device Ambient Backscatter Communication and Sensing Enabled by OFDM-AFDM Symbiotic Radio
Katia Abtouche, Fikiri Salum Uledi, Ayoub Ammar Boudjelal +4
This paper presents a novel symbiotic radio system for integrated sensing and backscatter communication (ISABC) technique that enables signal-domain interference-free coexistence o…
Waveform Coexistence-Driven RSMA: A Pioneering Strategy for Future 6G Networks
Kenza Abela, Shaima Abidrabbu, Ayoub Ammar Boudjelal +1
Two critical approaches have emerged in the literature for the successful realization of 6G wireless networks: the coexistence of multiple waveforms and the adoption of non-orthogo…
Redefining Orthogonal Co-Existence: A Mother Waveform Framework for DFT-Based Waveforms
Ayoub Ammar Boudjelal, Rania Yasmine Bir, Huseyin Arslan
In this paper, we introduce the concept of a mother waveform to address key challenges in 5th generation (5G) and 6th generation (6G) networks, including spectral efficiency, backw…
