What is DBPSK (Differential Binary Phase Shift Keying)?

The DPSK means “Differential phase-shift keying”. It is one sort of phase modulation utilized to send information by modifying the carrier wave’s phase. The signal phase follows the high or low state of the previous component. This DPSK strategy doesn’t require a reference oscillator. DPSK modulation doesn’t require the carrier signals toward the end of the receiver circuit. Hence compound circuits are not needed.
