Coupled-Band ESSFM for Low-Complexity DBP
<|reference_start|>Coupled-Band ESSFM for Low-Complexity DBP: 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 0.91 dB gains w.r.t. dispersion compensation with only 74, 161, or 681 real multiplications/2D-symbol, improving significantly on existing DBP techniques.<|reference_end|>
