Abstract:
An optical differentially phase shift keyed or DPSK binary signal which in the event of phase changes exhibits amplitude reductions and is phase-demodulated is provided. The received optical DPSK binary signal is additionally amplitude-demodulated and resulting phase and amplitude information is evaluated.
