Tensor-based Space Debris Detection for Satellite Mega-constellations
Olivier Daoust, Hasan Nayir, Irfan Azam +2
Thousands of satellites, asteroids, and rocket bodies break, collide, or degrade, resulting in large amounts of space debris in low Earth orbit. The presence of space debris poses…
Channel Estimation Using RIDNet Assisted OMP for Hybrid-field THz Massive MIMO Systems
Hasan Nayir, Erhan Karakoca, Ali Görçin +1
The terahertz (THz) band radio access with larger available bandwidth is anticipated to provide higher capacities for next-generation wireless communication systems. However, highe…
Measurement-Based Modeling of Short Range Terahertz Channels and Their Capacity Analysis
Erhan Karakoca, Hasan Nayir, Güneş Karabulut Kurt +1
In this work, extensive propagation characteristics of short range 240 to 300 GHz terahertz (THz) channels are mapped based on a measurement campaign conducted utilizing a novel, t…
RIDNet Assisted cGAN Based Channel Estimation for One-Bit ADC mmWave MIMO Systems
Erhan Karakoca, Hasan Nayir, Ali Görçin +1
The estimation of millimeter wave (mmWave) massive multiple input multiple output (MIMO) channels becomes compelling when one-bit analog to digital converters (ADCs) are utilized.…
Experimental Assessment of Misalignment Effects in Terahertz Communications
Hasan Nayir, Erhan Karakoca, Güneş Karabulut Kurt +1
Terahertz (THz) frequencies are important for next generation wireless systems due to the advantages in terms of large available bandwidths. On the other hand, the limited range du…
