Quantifying the Reality Gap for RL-Based UAV Placement at mmWave and Sub-THz
Abdullateef Almohamad, Mostafa Ibrahim, Sabit Ekin +1
Reinforcement learning (RL) policies for unmanned aerial vehicle (UAV) placement in mmWave and sub-terahertz networks are typically trained on simplified analytical channels. We qu…
The Anatomy of RF Chains: Metrics, Measures, and Operating Efficiency
Leonid Belostotski, Arjuna Madanayake, John Nielsen +6
In 1958, Haus and Adler [1] introduced the concept of noise measure. Noise measure is a single quantitative metric that provides a comprehensive basis for comparing devices (indivi…
Theoretical Foundations of Waste Factor and Waste Figure with Applications to Fixed Wireless Access and Relay Systems
Nurullah Sevim, Mostafa Ibrahim, Sabit Ekin +1
The exponential rise in energy consumption across wireless communication systems, particularly in anticipation of next-generation wireless systems, necessitates rigorous frameworks…
Anticipating Optical Availability in Hybrid RF/FSO Links Using RF Beacons and Deep Learning
Mostafa Ibrahim, Arsalan Ahmad, Sabit Ekin +4
Radio frequency (RF) communications offer reliable but low data rates and energy-inefficient satellite links, while free-space optical (FSO) promises high bandwidth but struggles w…
Free-Space Optical Channel Turbulence Prediction: A Machine Learning Approach
Md Zobaer Islam, Ethan Abele, Fahim Ferdous Hossain +3
Channel turbulence is a formidable obstacle for free-space optical (FSO) communication. Anticipation of turbulence levels is highly important for mitigating disruptions but has not…
Positioning Error Impact Compensation through Data-Driven Optimization in User-Centric Networks
Waseem Raza, Fahd Ahmed Khan, Muhammad Umar Bin Farooq +2
The performance of user-centric ultra-dense networks (UCUDNs) hinges on the Service zone (Szone) radius, which is an elastic parameter that balances the area spectral efficiency (A…
