摘要

A learned perturbation -aided advanced digital backpropagation (LP-ADBP) with nonlinear compensation fusion is proposed for subcarrier-multiplexing systems. 1-Step and 5-Step LP-ADBP provide similar performance as 5-Step and 10-Step ADBP but save similar to 73.3% and similar to 44.5% complexity, respectively.
