Emulating UAV Motion by Utilizing Robotic Arm for mmWave Wireless Channel Characterization

1 code implementation20 Jun 2020 Amit Kachroo, Collin A. Thornton, Md Arifur Rahman Sarker, Wooyeol Choi, He Bai, Ickhyun Song, John O'Hara, Sabit Ekin

In this paper, millimeter wave (mmWave) wireless channel characteristics (Doppler spread and path loss modeling) for Unmanned Aerial Vehicles (UAVs) assisted communication is analyzed and studied by emulating the real UAV motion using a robotic arm.

Dispersion from Diffuse Reflectors and its Effect of Terahertz Wireless Communication Performance

no code implementations1 Apr 2021 Russ Messenger, Karl Strecker, Sabit Ekin, John O'Hara

This work investigates the temporal dispersion of a wireless terahertz communication signal caused by reflection from a rough (diffuse) surface, and its subsequent impact on symbol error rate versus data rate.
