Perturbation-based Sequence Selection for Probabilistic Amplitude Shaping

arXiv:2407.09006

Abstract

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 dB SNR gain for single-polarized 256-QAM transmission over a long-haul fiber link.
