Perturbation-based Sequence Selection for Probabilistic Amplitude Shaping
<|reference_start|>Perturbation-based Sequence Selection for Probabilistic Amplitude Shaping: We introduce a practical sign-dependent sequence selection metric for probabilistic amplitude shaping and propose a simple method to predict the gains in signal-to-noise ratio (SNR) for sequence selection. The proposed metric provides a $0.5$ dB SNR gain for single-polarized 256-QAM transmission over a long-haul fiber link.<|reference_end|>
