Abstract
A modified weighted learned digital backpropagation (M-W-LDBP) with pre-optimization is proposed for fiber nonlinearity compensation in high-symbol-rate coherent systems. Compared with LDBP, M-W-LDBP exhibits 1/0.7 dB signal-to-noise ratio gain in 90/128-GBaud systems, respectively. © 2021 The Author(s)
