DPSK

(Differential Phase Shift Keying) A common form of phase modulation used in analog modems. DPSK does not require complex demodulation circuitry and is less susceptible to random phase changes in the transmitted waveform. See PSK, FSK and QPSK.

The constant intensity downstream DPSK signal is demodulated by a 1-bit delayed interferometer (DI) and balanced photo diodes.
The BER for coherent DPSK demodulation can be calculated as[6]

In the first system for optical signal modulation in all three channels differential binary phase shift keying (DPSK) was used, in the second--the intensity modulation (IM) and in the third--polarization shift keying were used, while the fourth is a combined transmission system, where for the first channels optical signal modulation NRZ DPSK was used, for the second channel--NRZ--OOK and third--2--POLSK.
