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…
LoRa Backscatter Communications: Temporal, Spectral, and Error Performance Analysis
Ganghui Lin, Ahmed Elzanaty, Mohamed-Slim Alouini
LoRa backscatter (LB) communication systems can be considered as a potential candidate for ultra low power wide area networks (LPWAN) because of their low cost and low power consum…
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…
Coverage analysis of Tethered UAV-assisted Large Scale Cellular Networks
Safa Khemiri, Mustafa A. Kishk, Mohamed-Slim Alouini
One of the major challenges slowing down the use of unmanned aerial vehicles (UAVs) as aerial base stations (ABSs) is the limited on-board power supply which reduces the UAV's flig…
