Channel Prediction for mmWave Ground-to-Air Propagation under Blockage
Wahab Khawaja, Ozgur Ozdemir, Ismail Guvenc
Ground-to-air (GA) communication using unmanned aerial vehicles (UAVs) has gained popularity in recent years and is expected to be part of 5G networks and beyond. However, the GA l…
EMR: A New Metric to Assess the Resilience of Directional mmWave Channels to Blockages
Fatih Erden, Ozgur Ozdemir, Ismail Guvenc +1
Millimeter-wave (mmWave) communication systems require narrow beams to increase communication range. If the dominant communication direction is blocked by an obstacle, an alternati…
RF-Based Low-SNR Classification of UAVs Using Convolutional Neural Networks
Ender Ozturk, Fatih Erden, Ismail Guvenc
This paper investigates the problem of classification of unmanned aerial vehicles (UAVs) from radio frequency (RF) fingerprints at the low signal-to-noise ratio (SNR) regime. We us…
Attenuation of Several Common Building Materials in Millimeter-Wave Frequency Bands: 28, 73 and 91 GHz
Nozhan Hosseini, Mahfuza Khatun, Changyu Guo +5
Future cellular systems will make use of millimeter wave (mmWave) frequency bands. Many users in these bands are located indoors, i.e., inside buildings, homes, and offices. Typica…
Outdoor mmWave Base Station Placement: A Multi-Armed Bandit Learning Approach
Fatih Erden, Chethan K. Anjinappa, Ender Ozturk +1
Base station (BS) placement in mobile networks is critical to the efficient use of resources in any communication system and one of the main factors that determines the quality of…
Localization with Deep Neural Networks using mmWave Ray Tracing Simulations
Udita Bhattacherjee, Chethan Kumar Anjinappa, LoyCurtis Smith +2
The world is moving towards faster data transformation with more efficient localization of a user being the preliminary requirement. This work investigates the use of a deep learni…
28 GHz mmWave Channel Measurements: A Comparison of Horn and Phased Array Antennas and Coverage Enhancement Using Passive and Active Repeaters
Ozgur Ozdemir, Fatih Erden, Ismail Guvenc +2
Propagation channel characteristics are substantially different in sub-6 GHz and millimeter-wave (mmWave) bands. A typical mmWave link experiences more than an order-of-magnitude l…
Multiple Ray Received Power Modeling for mmWave Indoor and Outdoor Scenarios
Wahab Khawaja, Ozgur Ozdemir, Fatih Erden +2
Millimeter-wave (mmWave) frequency bands are expected to be used for future 5G networks due to the availability of large unused spectrum. However, the attenuation at mmWave frequen…
