Self-Attention Transformer-Based Detector for Faster-than-Nyquist Signaling
Nurettin Safak, Osman Tokluoglu, Enver Cavus
In this study, a novel encoder-only Transformer-based receiver architecture is presented for BPSK signals transmitted over Faster-than-Nyquist (FTN) signaling channels that introduce intentional inter-symbol interference (ISI) with a compression factor of $τ=0.8$. A complete end-…
