Zadoff-Chu Sequences for Chirp-Domain Communication: Diversity-Complexity Tradeoffs in Doubly Dispersive Channels
Rawan Alghamdi, Moahmed Siala, Tareq Y. Al-Naffouri +1
Orthogonal frequency-division multiplexing (OFDM) combats multipath-induced time dispersion by dividing the channel into narrowband sub-channels. However, when the channel also exh…
Angle-of-Arrival Estimation of Narrow Gaussian Beams for Mobile FSO Platforms
Ming-Cheng Tsai, Muhammad Salman Bashir, Mohamed-Slim Alouini
Due to the narrow beamwidths of laser Gaussian beams, accurate tracking of laser beam's angle-of-arrival is an important problem in mobile free-space optical communications. In mos…
Harnessing the Potential of Optical Communications for the Metaverse
Baha Eddine Youcef Belmekki, Abderrahmen Trichili, Boon S. Ooi +1
The Metaverse is a digital world that offers an immersive virtual experience. However, the Metaverse applications are bandwidth-hungry and delay-sensitive that require ultrahigh da…
Machine Learning-Based Automatic Cardiovascular Disease Diagnosis Using Two ECG Leads
Cheng Guo, Sajid Ahmed, Mohamed-Slim Alouini
The state-of-the-art cardiovascular disease diagnosis techniques use machine-learning algorithms based on feature extraction and classification. In this work, in contrast to a conv…
Lidar-Assisted Acquisition of Mobile Airborne FSO Terminals in a GPS-Denied Environment
Heyou Liu, Muhammad Salman Bashir, Mohamed-Slim Alouini
For acquisition of narrow-beam free-space optical (FSO) terminals, a Global Positioning System (GPS) is typically required for coarse localization of the terminal. However, the GPS…
High-rate Reliable Communication using Multi-hop and Mesh THz/FSO Networks
Praveen Kumar Singya, Behrooz Makki, Antonio D'Errico +1
In this work, we consider multi-hop and mesh hybrid teraHertz/free-space optics (THz/FSO)-based backhaul networks for high data-rate communications. The results are presented for t…
