Impact of 3D Antenna Radiation Pattern in UAV Air-to-Ground Path Loss Modeling and RSRP-based Localization in Rural Area

no code implementations24 Jul 2023 Sung Joon Maeng, Hyeokjun Kwon, Ozgur Ozdemir, İsmail Güvenç

By analyzing reference signal received power (RSRP) using path loss models that account for antenna patterns, we observed that our measurement results, obtained at different UAV heights, aligned well with the two-ray path loss model when incorporating the measured antenna pattern.

RF SSSL by an Autonomous UAV with Two-Ray Channel Model and Dipole Antenna Patterns

no code implementations28 May 2023 Hyeokjun Kwon, Sung Joon Maeng, Ismail Guvenc

In this paper, the efficacy of the proposed localization approaches is examined based on these two main localization requirements through computer simulations.

RF Signal Source Search and Localization Using an Autonomous UAV with Predefined Waypoints

no code implementations17 Jan 2023 Hyeokjun Kwon, Ismail Guvenc

The use of unmanned aerial vehicles (UAVs) for signal source search and localization (SSSL) can have significant advantages when compared to terrestrial-based approaches, due to the ease of capturing RF signals at higher altitudes and the autonomous 3D navigation capabilities of UAVs.

Neighborhood Reconstructing Autoencoders

1 code implementation NeurIPS 2021 Yonghyeon LEE, Hyeokjun Kwon, Frank Park

Unlike existing graph-based methods that attempt to encode the training data to some prescribed latent space distribution -- one consequence being that only the encoder is the object of the regularization -- NRAE merges local connectivity information contained in the neighborhood graphs with local quadratic approximations of the decoder function to formulate a new neighborhood reconstruction loss.
