ABSTRACT:
Demodulating an optical Differential Phase-Shift Keying (DPSK) signal is accomplished using a self-homodyne receiver for receiving the optical signal. A converter converts the optical signal received by the self-homodyne receiver into a representative electrical signal. A processor that processes the representative electrical signal using decision feedback multi-symbol detection in order to obtain a decision variable that indicates a differential phase-shift in the optical signal.
