Pre- and Post-Exercise Monitoring of Physiological Skin States in Sportsmen Using 77 GHz FMCW Radar and Wavelet Scattering Transform
Vijith Varma Kotte, Muhammad Mahboob Ur Rahman, Sajid Ahmed +1
This paper presents a contactless radar sensing framework that classifies physiologically-induced changes in the superficial skin layer following intense fixed-duration physical ac…
Real-Time Symbol-Domain OFDM Radar in an OpenAirInterface 5G Base Station With O-RAN Sensing Services
Karim Saifullin, Sajid Ahmed, Mohamed-Slim Alouini
This paper presents a real-time orthogonal frequency-division multiplexing (OFDM) radar embedded in the OpenAirInterface (OAI) 5G base-station process. The radar removes communicat…
Frequency Diverse Arrays: Fundamentals, Key Insights, and Future Directions
Bang Huang, Sajid Ahmed, Wenkai Jia +2
Frequency diverse arrays (FDA) have attracted sustained interest as a promising architecture for introducing range-dependent responses into array systems. Unlike conventional phase…
Activity Recognition Using mm-Wave Radar and Deep Learning: Prayer Tracker Case Study
Karim Saifullin, Sajid Ahmed, Mohamed-Slim Alouini
The issue of privacy has gained significant attention in recent times. Many real-world applications increasingly require the use of sensitive data, such as in surveillance or track…
Design of Frequency Index Modulated Waveforms for Integrated SAR and Communication on High-Altitude Platforms (HAPs)
Bang Huang, Sajid Ahmed, Mohamed-Slim Alouini
This paper, addressing the integration requirements of radar imaging and communication for High-Altitude Platform Stations (HAPs) platforms, designs a waveform based on linear freq…
Exploring the Synergy: A Review of Dual-Functional Radar Communication Systems
Ali Hanif, Sajid Ahmed, Tareq Y. Al-Naffouri +1
This review paper examines the concept and advancements in the evolving landscape of Dual-functional Radar Communication (DFRC) systems. Traditionally, radar and communication syst…
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…
Generalized Fully Coherent Closed-form Receiver Design for Joint Radar and Communication System
Muhammad Zubair, Sajid Ahmed, Mohamed-Slim Alouini
In conventional radar, the transmission of the same waveform is repeated after a predefined interval of time called pulse-repetition-interval (PRI). This technique helps to estimat…
Modeling of Viral Aerosol Transmission and Detection
Maryam Khalid, Osama Amin, Sajid Ahmed +2
In this paper, we propose studying the disease spread mechanism in the atmosphere as an engineering problem. Aerosol transmission is the most significant mode among the viral trans…
Frequency Diverse Array Radar: New Results and Discrete Fourier Transform Based Beampattern
Muhammad Zubair, Sajid Ahmed, Mohamed-Slim Alouini
In the phased-array radar (PAR) signals from each antenna are transmitted at the same carrier frequency, which yields narrowly focused only angle dependent beampattern. In contrast…
Communication Through Breath: Aerosol Transmission
Maryam Khalid, Osama Amin, Sajid Ahmed +2
Exhaled breath can be used in retrieving information and creating innovative communication systems. It contains several volatile organic compounds (VOCs) and biological entities th…
