" Spectrum-Anom-code"

"This data package contains the case-study feature data and experimental materials used for reproducing the results in the manuscript. The feature data are derived from a real VHF long-term spectrum monitoring case. Different parameterized anomalous spectrum behavior patterns are injected into the monitoring sequence, including spurious interference, periodic short-duration interference, spectrum silence, and service absence. Each pattern is provided under different severity levels.The files contain relative time indices, multidimensional feature values, and binary anomaly labels. These data are used to evaluate classical unsupervised baselines, reconstruction-based deep temporal models, and reference-pipeline variants. The package supports reproduction of point-level metrics, event-level metrics, PR-AUC, mIoU, and time-to-detect results reported in the manuscript."
