Low complexity fiber nonlinearity compensation scheme fusing single-channel digital back propagation with dual phase-conjugate twin waves for DSCM-WDM system
{{output}}
In coherent systems combining digital subcarrier multiplexing (DSCM) and wavelength division multiplexing (WDM), signals are subject to self-subcarrier nonlinearity (SSN), cross-subcarrier nonlinearity (CSN), and cross-phase modulation (XPM) after optical fibe... ...
