Abstract
Rapid advancements in deep learning (DL) and the availability of the large data sets have made the adoption of DL highly appealing across various fields. Wireless communication systems, including future 6G systems are anticipated to incorporate intelligent components like automatic modulation classification (AMC) for the cognitive radio and dynamic spectrum access. However, DL-based AMC models are susceptible to the adversarial attacks, which consist of crafted perturbations that aim to alternate the decision of a victim model. This study focuses on investigating and uncovering modern modulation classifiers’ vulnerability to the adversarial threats. Though attacks of this nature inherently jeopardize DL-based classifiers, contemporary attack methods typically exhibit diminished impact at the lower perturbation levels. Therefore, we introduce a novel attack approach that exploits the Riemannian manifold properties of the intricate neural networks, yielding adversarial samples with heightened efficacy at the lower perturbation powers. We thoroughly evaluate how effective various defense techniques are and demonstrate our proposed attack method’s ability to thwart them. The findings of this study shed light on the limitations and vulnerabilities of the DL-based AMC models in the face of the adversarial attacks. By addressing these challenges, we can enhance the robustness and security of these models, and pave the way for their reliable deployment in practical wireless communication systems, including the future 6G networks.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
