This repository includes codes for proposed approaches and all the baselines of paper 10.1109/TSP.2025.3531872: Dynamic Spectrum Cartography: Reconstructing Spatial-Spectral-Temporal Radio Frequency Map via Tensor Completion.
Get started by simply running Dynamic_SC.m. This will return a visualization result together with reconstruction errors, under a ray-tracing scenario.
To reproduce more results, please download dataset 'Param_R8_sigma8_K64_T600_v0.1.mat' at https://drive.google.com/file/d/1Yi_7MrMLGWe_1Br9JQPOXhnVivjY62jE/view?usp=sharing, and 'Param_R8_sigma8_K64_T600_v0.01.mat' at https://drive.google.com/file/d/1hxxoUhHVFKmSZKtIRBWlkoeCxOtfJIYR/view?usp=sharing.
Also try to customize a scenario using the files in Dynamic_SC_Customize, where a radio map generator is offered.
Directory Dynamic_SC_LongTerm offers the codes of the proposed IncreDSC algorithm under long-term scenario, where the activated emitters change over time. To reproduce the result, download dataset 'Param_sigma8_K64_T600_v0.1_LT.mat' at https://drive.google.com/file/d/12Vz3Nr3PsZJUZxUsqbQw68pgxXWK05yJ/view?usp=sharing.
