30% Reach Increase via Low-complexity Hybrid HD/SD FEC and Nonlinearity-tolerant 4D Modulation
Gabriele Liga, Bin Chen, Sjoerd van der Heide +4
Current optical coherent transponders technology is driving data rates towards 1 Tb/s/λand beyond. This trend requires both high-performance coded modulation schemes and efficient…
On Parameter Optimization of Product Codes for Iterative Bounded Distance Decoding with Scaled Reliability
Alireza Sheikh, Alexandre Graell i Amat, Gianluigi Liva +1
We use density evolution to optimize the parameters of binary product codes (PCs) decoded based on the recently introduced iterative bounded distance decoding with scaled reliabili…
On Product Codes with Probabilistic Amplitude Shaping for High-Throughput Fiber-Optic Systems
Alireza Sheikh, Alexandre Graell i Amat, Alex Alvarado
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 d…
A novel soft-aided bit-marking decoder for product codes
Gabriele Liga, Alireza Sheikh, Alex Alvarado
We introduce a novel soft-aided hard-decision decoder for product codes adopting bit marking via updated reliabilities at each decoding iteration. Gains up to 0.8 dB vs. standard i…
Binary Message Passing Decoding of Product-like Codes
Alireza Sheikh, Alexandre Graell i Amat, Gianluigi Liva
We propose a novel binary message passing decoding algorithm for product-like codes based on bounded distance decoding (BDD) of the component codes. The algorithm, dubbed iterative…
Binary Message Passing Decoding of Product Codes Based on Generalized Minimum Distance Decoding
Alireza Sheikh, Alexandre Graell i Amat, Gianluigi Liva
We propose a binary message passing decoding algorithm for product codes based on generalized minimum distance decoding (GMDD) of the component codes, where the last stage of the G…
