Abstract: A modified adaptive digital backpropagation (A-DBP) algorithm based on intensity variance is proposed in this letter. In the simulation, a 25-GBd dual-polarization 16-quadrature amplitude modulation transmission system with a transmission distance of 2000 km is established to investigate the performance of the proposed A-DBP. The simulation results show that the proposed A-DBP can dynamically estimate the optimal fiber nonlinear coefficient &#x03B3;<sub>opt</sub> and achieve comparable or even better performance than the DBP with full knowledge of fiber. Moreover, the proposed A-DBP can achieve better performance compared with the previous A-DBP based on intensity variance. Moreover, the proposed A-DBP requires fewer iterations to determine &#x03B3;<sub>opt</sub> compared with the previous A-DBP based on intensity or phase variance.
