arXiv:2607. 08031v1 Announce Type: cross Abstract: The dynamics of communication environments induce significant distribution shifts across domains, challenging the generalization of deep learning-based automatic modulation classification (AMC) models.
arXiv:2608. 00796v1 Announce Type: cross Abstract: Automatic RF modulation recognition is of critical importance in spectrum monitoring, electronic warfare, and cognitive radio applications, where low signal-to-noise ratio (SNR) conditions and the growing diversity of modulation schemes limit the performance of existing methods.
The paper introduces Tri-PNet, a deep learning framework that jointly designs electromagnetic (EM), analog, and digital precoding for tri-hybrid multi-user MIMO OFDM systems. By leveraging Conformer architecture, Tri-PNet learns to select radiation patterns and perform hybrid precoding, achieving higher spectral efficiency than random EM precoding and conventional hybrid MIMO while maintaining low online complexity. The study evaluates two radiation-pattern modes—non-regular and 3GPP TR 38.901—showing robust performance even with imperfect channel state information.
The paper introduces FuseAMC, a lightweight decision‑fusion model that combines a residual CNN and a gradient‑boosted‑tree cumulant classifier for automatic modulation classification. By training a logistic‑regression meta‑combiner on the class‑posteriors of both models, FuseAMC achieves higher overall accuracy than either approach alone, especially improving performance at both low and high signal‑to‑noise ratios. The resulting system contains only about 0.2 million parameters, occupies a few megabytes, and requires roughly 3 MFLOPs per frame, enabling training and inference on a single CPU core suitable for embedded processors.
