Non-uniform step-size distribution is implemented for split-step based
nonlinear compensation in single-channel 112-Gb/s 16 quadrature
amplitude modulation (QAM) transmission. Numerical simulations of the
system including a 20 \times 80 km uncompensated link are performed
using logarithmic step size distribution to compensate signal
distortions. 50% of reduction in number of steps with respect to using
constant step sizes is observed. The performance is further improved by
optimizing nonlinear calculating position (NLCP) in case of using
constant step sizes while NLCP optimization becomes unnecessary when
using logarithmic step sizes, which reduces the computational effort due
to uniformly distributed nonlinear phase for all successive steps.
