Energy-Efficient Soft-Assisted Product Decoders
Christoffer Fougstedt, Alireza Sheikh, Alexandre Graell i Amat +2
We implement a 1-Tb/s 0.63-pJ/bit soft-assisted product decoder in a 28-nm technology. The decoder uses one bit of soft information to improve its net coding gain by 0.2 dB, reachi…

ASIC Implementation of Time-Domain Digital Backpropagation with Deep-Learned Chromatic Dispersion Filters
Christoffer Fougstedt, Christian Häger, Lars Svensson +2
We consider time-domain digital backpropagation with chromatic dispersion filters jointly optimized and quantized using machine-learning techniques. Compared to the baseline implem…
