A New Twist on Low-Complexity Digital Backpropagation
Stella Civelli, Debi Pada Jana, Enrico Forestieri +1
This work proposes a novel low-complexity digital backpropagation (DBP) method, with the goal of optimizing the trade-off between backpropagation accuracy and complexity. The metho…

Coupled-Band ESSFM for Low-Complexity DBP
Stella Civelli, Debi Pada Jana, Enrico Forestieri +1
We propose a novel digital backpropagation (DBP) technique that combines perturbation theory, subband processing, and splitting ratio optimization. We obtain 0.23 dB, 0.47 dB, or 0…
