On Product Codes With Probabilistic Amplitude Shaping for High-Throughput Fiber-Optic Systems [PDF]
IEEE Communications Letters, 2020 Probabilistic amplitude shaping (PAS) can flexibly vary the spectral efficiency (SE) of fiber-optic systems. In this paper, we demonstrate the application of PAS to bit-wise hard decision decoding (HDD) of product codes (PCs) by finding the necessary conditions to select the PC component codes. We show that PAS with PCs and HDD yields gains up to $2.7$

Multicarrier Faster-Than-Nyquist Based on Efficient Implementation and Probabilistic Shaping
IEEE Access, 2021 The conventional multicarrier faster-than-Nyquist (MFTN) achieves the spectral efficiency (SE) gain by deep compression. However, deep compression leads to severe intersymbol interference (ISI) or intercarrier interference (ICI).
