An analytical tool based on the moment generating function of the receiver decision variable that can evaluate the impact of multi-format in-band crosstalk in optical differential quadrature phase-shift keying (DQPSK) systems is presented. It is shown that the on-off keying (OOK) interferer is the most detrimental interferer in terms of performance degradation. A Monte Carlo simulation tool validates the analytical results.
