Spatial Transformers for Radio Map Estimation
Pham Q. Viet, Daniel Romero
Radio map estimation (RME) involves spatial interpolation of radio measurements to predict metrics such as the received signal strength at locations where no measurements were coll…
Path Planning for Aerial Relays via Probabilistic Roadmaps
Pham Q. Viet, Daniel Romero
Autonomous uncrewed aerial vehicles (UAVs) can be utilized as aerial relays to serve users far from terrestrial infrastructure. Unfortunately, existing algorithms for aerial relay…
Implicit Channel Charting with Application to UAV-aided Localization
Pham Q. Viet, Daniel Romero
Traditional localization algorithms based on features such as time difference of arrival are impaired by non-line of sight propagation, which negatively affects the consistency tha…
Aerial Base Station Placement Leveraging Radio Tomographic Maps
Daniel Romero, Pham Q. Viet, Geert Leus
Mobile base stations on board unmanned aerial vehicles (UAVs) promise to deliver connectivity to those areas where the terrestrial infrastructure is overloaded, damaged, or absent.…
