In the canonical digital back-propagation (CDBP) of compensating for optical fiber nonlinearity, the aim is to invert the nonlinear Schrödinger equation (NSE). Therefore, the virtual link mirrors the fiber link for all the deterministic parameters. In theory, it can eliminate the deterministic linea...
