UWB Air-to-Ground Propagation Channel Measurements and Modeling using UAVs
Wahab Khawaja, Ozgur Ozdemir, Fatih Erden +2
This paper presents an experimental study of the air-to-ground (AG) propagation channel through ultrawideband(UWB) measurements in an open area using unmanned-aerial-vehicles (UAVs…
Multilinear SVD for Millimeter Wave Channel Parameter Estimation
Macey Ruble, Ismail Guvenc
Fifth generation (5G) cellular standards are set to utilize millimeter wave (mmWave) frequencies, which enable data speeds greater than 10 Gbps and sub-centimeter localization accu…
Indoor Coverage Enhancement for mmWave Systems with Passive Reflectors: Measurements and Ray Tracing Simulations
Wahab Khawaja, Ozgur Ozdemir, Yavuz Yapici +3
The future 5G networks are expected to use millimeter wave (mmWave) frequency bands, mainly due to the availability of large unused spectrum. However, due to high path loss at mmWa…
Temporal and Spatial Characteristics of mmWave Propagation Channels for UAVs
Wahab Khawaja, Ozgur Ozdemir, Ismail Guvenc
Unmanned aerial vehicles~(UAVs) are envisioned to be an integral part of future 5G communication systems. The agile nature of UAVs for serving users at different locations can help…
A Survey of Air-to-Ground Propagation Channel Modeling for Unmanned Aerial Vehicles
Wahab Khawaja, Ismail Guvenc, David Matolak +2
In recent years, there has been a dramatic increase in the use of unmanned aerial vehicles (UAVs), particularly for small UAVs, due to their affordable prices, ease of availability…
Autonomous Tracking of Intermittent RF Source Using a UAV Swarm
Farshad Koohifar, Ismail Guvenc, Mihail L. Sichitiu
Localization of a radio frequency (RF) transmitter with intermittent transmissions is considered via a group of unmanned aerial vehicles (UAVs) equipped with omnidirectional receiv…
Non-Orthogonal Multiple Access for Mobile VLC Networks with Random Receiver Orientation
Yavuz Yapici, Ismail Guvenc
We consider a downlink multiuser visible light communications (VLC) network where users randomly change their location and vertical orientation. The non-orthogonal multiple access…
