DC-FTNet: A Parameter-Free Fourier-Based Lightweight Network for Automatic Modulation Classification in OTFS

Automatic modulation classification (AMC) for orthogonal time frequency space (OTFS) systems is crucial in non-cooperative scenarios. While vision-transformer (ViT)-based classifiers achieved high accuracy, they suffered from quadratic computational complexity due to self-attention. To address this limitation, this let...
