On Product Codes with Probabilistic Amplitude Shaping for High-Throughput Fiber-Optic Systems
Journal article, 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 dB and SE improvement up to approximately 1 bit/channel use compared to using PCs with uniform signaling and HDD. Furthermore, we employ the recently introduced iterative bounded distance decoding with combined reliability of PCs to improve the performance of PAS with PCs and HDD.
