Aerial Spectrum Surveying: Radio Map Estimation with Autonomous UAVs
Daniel Romero, Raju Shrestha, Yves Teganya +1
Radio maps are emerging as a popular means to endow next-generation wireless communications with situational awareness. In particular, radio maps are expected to play a central rol…
Data-Driven Spectrum Cartography via Deep Completion Autoencoders
Yves Teganya, Daniel Romero
Spectrum maps, which provide RF spectrum metrics such as power spectral density for every location in a geographic area, find numerous applications in wireless communications such…
Fast Decentralized Linear Functions via Successive Graph Shift Operators
Siavash Mollaebrahim, Daniel Romero, Baltasar Beferull-Lozano
We study decentralized designing of the graph shift operators to implement linear transformations between graph signals. Since this operator captures the local structure of the gra…
Non-cooperative Aerial Base Station Placement via Stochastic Optimization
Daniel Romero, Geert Leus
Autonomous unmanned aerial vehicles (UAVs) with on-board base station equipment can potentially provide connectivity in areas where the terrestrial infrastructure is overloaded, da…
Location-free Spectrum Cartography
Yves Teganya, Daniel Romero, Luis Miguel Lopez Ramos +1
Spectrum cartography constructs maps of metrics such as channel gain or received signal power across a geographic area of interest using spatially distributed sensor measurements.…
