Abstract
Based on the dispersion-folded digital back-propagation (DBP) method, we propose a low-complexity digital nonlinearity-compensation scheme to enhance the system performance of optical phase conjugation (OPC)-aided transmission whilst preserving the low computational requirement of dispersion-folded DBP. When the transmission reach is increased, the computational efficiency of the proposed scheme becomes more apparent compared with conventional DBP while the performance penalty is negligible.
