Abstract
When a differential phase-shift keying signal is contaminated by nonlinear phase noise, various models to evaluate the error probability are compared. The simplest method is based on the Q factor. The exact method takes into account the dependence between amplifier noise and nonlinear phase noise. All approximated models underestimate both the error probability and the required signal-to-noise ratio.
