Geometric Inductive Biases for Semi-Supervised Equalization: The Constellation-Aware Transformer

CAT jointly processes the known constellation and received signals from the first layer, with a bidirectional FIR signal branch for inter-symbol interference, reducing pilot requirements through per-block semi-supervised adaptation; the benefit still requires sufficient pilots and receiver-side training, rather than enabling unsupervised or zero-shot decoding across channels.
