Regular Perturbation on the Group-Velocity Dispersion Parameter for Dual-Polarization Short-Reach Systems
Dario Cellini, Vinícius Oliari, Erik Agrell +3
The Manakov equation governs the propagation of signals in dual-polarization systems. Its solution is usually approximated by regular perturbation on the nonlinear Kerr parameter.…
Channel Estimation and LDPC Decoding for Bursty Phase Noise
Han Cui, Frank R. Kschischang, Magnus Karlsson +1
Time-varying distortions in communication systems can significantly degrade the performance of soft-decision forward error correction. This paper presents a burst-aware (BA) low-de…
PIDT: Physics-Informed Digital Twin for Optical Fiber Parameter Estimation
Zicong Jiang, Magnus Karlsson, Erik Agrell +1
We propose physics-informed digital twin (PIDT): a fiber parameter estimation approach that combines a parameterized split-step method with a physics-informed loss. PIDT improves a…
