A unified online probabilistic framework that represents each reflecting facade as a virtual anchor (VA) and couples Bayesian VA localization, multipath attribution, and material inference to produce stable material posteriors and material-labeled environment maps is proposed.

Unmanned aerial vehicle (UAV)-based interference source localization is increasingly important in dense 5G-Advanced and emerging 6G networks, where unknown interferers degrade communication reliability and bias measurement-driven channel modeling. However, propagation uncertainty caused by multipath, blockage, and non-...
A memory-based online sparse variational Gaussian process (M-OSVGP) method that efficiently updates radio maps from streaming spectrum measurements and extends M-OSVGP with a grid-assisted online inducing point selection (GOIPS) algorithm that dynamically adapts the number and locations of inducing points based on meas...
