Cost-Gain Analysis of Sequence Selection for Nonlinearity Mitigation
Stella Civelli, Marco Secondini
We propose a low-complexity sign-dependent metric for sequence selection and study the nonlinear shaping gain achievable for a given computational cost, establishing a benchmark fo…

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…

Coherent transceiver architecture enabling data transmission and optical identification
Stella Civelli, Marco Secondini, Pantea Nadimi Goki +1
We propose a coherent transceiver architecture able to transmit information and enhance the security of the optical network by identifying other optical systems and subsystems. Sim…
