Both degrading differential phase-shift keying signals, the standard deviation of nonlinear phase-noise-induced differential phase is about three times that from IFWM even in highly dispersive transmission systems.application/pdf156805 bytesapplication/pdfzh-TWDifferential phase-shift keying (DPSK)fiber nonlinearitiesintrachannel four-wave mixing (IFWM)nonlinear phase noisejournal articlehttp://ntur.lib.ntu.edu.tw/bitstream/246246/200611150121692/1/3097.pdf
