Zusammenfassung: | We introduce decision-feedback-based novel realizations of substantially reduced complexity for the recently proposed multichip differential phase-shift keying (MC-DPSK) advanced modulation formats, and interpret the operation of the resulting simplified receivers as synthesizing a lower noise reference for differential phase detection. Full propagation simulations indicate that the resulting binary phase MC-DPSK with three (four) chips display a bit-error-rate advantage of nearly three (four) orders of magnitude relative to conventional DPSK over a nonlinear phase fiber channel |
