Multi-Year Spectral Structure of 6G Candidate Bands at 2.7 GHz and 4.4 GHz
Amir Hossein Fahim Raouf, Ismail Guvenc
Mid-band spectrum between 2 and 8 GHz is a critical resource for sixth-generation (6G) systems as it uniquely balances favorable propagation characteristics with scalable bandwidth…
Height-Dependent Spectrum Activity Measurements and Modeling: A Case Study with FM Radio Bands
Sung Joon Maeng, Amir Hossein Fahim Raouf, Ozgur Ozdemir +2
The increasing demand for wireless connectivity necessitates advanced spectrum modeling to enable efficient spectrum sharing for next-generation aerial communications. While tradit…
LarS-Net: A Large-Scale Framework for Network-Level Spectrum Sensing
Hao Guo, Ruoyu Sun, Amir Hossein Fahim Raouf +3
As the demand of wireless communication continues to rise, the radio spectrum (a finite resource) requires increasingly efficient utilization. This trend is driving the evolution f…
Beyond Path Loss: Altitude-Dependent Spectral Structure Modeling for UAV Measurements
Amir Hossein Fahim Raouf, İsmail Güvenç
This paper presents a measurement-based framework for characterizing altitude-dependent spectral behavior of signals received by a tethered Helikite unmanned aerial vehicle (UAV).…
Inter-Year Transfer of Altitude-Dependent Spectrum Activity Models Using Minimal Calibration
Amir Hossein Fahim Raouf, İsmail Güvenc
This paper studies the transferability of altitude-dependent spectrum activity models and measurements across years. We introduce a physics-informed, mean-only stochastic-geometry…
AI-Driven Low-Altitude Economy: Spectrum, Mobility, and Validation
Kürşat Tekbıyık, Amir Hossein Fahim Raouf, İsmail Güvenç +3
The Low Altitude Economy (LAE) network, with its transformative capabilities, is a candidate to become one of the major technological developments of the next decade for air mobili…
Optimizing Energy-Harvesting Hybrid VLC/RF Networks with Random Receiver Orientation
Amir Hossein Fahim Raouf, Chethan Kumar Anjinappa, Ismail Guvenc
This paper investigates an indoor hybrid visible light communication (VLC) and radio frequency (RF) scenario with two-hop downlink transmission. A light emitting diode (LED) transm…
Spectrum Monitoring and Analysis in Urban and Rural Environments at Different Altitudes
Amir Hossein Fahim Raouf, Sung Joon Maeng, Ismail Guvenc +2
Due to the scarcity of spectrum resources, the emergence of new technologies and ever-increasing number of wireless devices operating in the radio frequency spectrum lead to data c…
Performance Analysis of Quantum Key Distribution in Underwater Channels
Amir Hossein Fahim Raouf
The current literature on quantum key distribution (QKD) is mainly limited to the transmissions over fiber optic, atmospheric or satellite links and are not directly applicable to…
