DOI: 10.1109/lsp.2023.3257723
Abstract: Tensor-based spectrum cartography (SC) has received increasing interests for recovering multi-dimensional radio map (RM) from sparse measurements. However, existing tensor-based SC methods largely depend on an ideal assumption, that the sparse measurements are regularly located… read more here.

DOI: 10.1109/tsp.2020.2993530
Abstract: Spectrum cartography aims at estimating power propagation patterns over a geographical region across multiple frequency bands (i.e., a radio map)—from limited samples taken sparsely over the region. Classic cartography methods are mostly concerned with recovering… read more here.
