ML-assisted Subband Learned Digital Backpropagation for Nonlinearity Compensation in Wideband Optical Systems
Evgeny Shevelev, Oleg Sidelnikov, Vitaly Danilko +2
Digital backpropagation (DBP) is one of the most effective techniques for compensating nonlinear distortions in coherent optical fiber communication systems. However, its practical…

Low-complexity neural network equalization for long-haul coherent transmission with cascaded semiconductor optical amplifiers
S. Bogdanov, S. Sygletos, O. Sidelnikov +3
In this letter, we numerically investigate a long-haul coherent data transmission system with a cascade of semiconductor optical amplifiers (SOAs). We exploit low-complexity neural…
