WebIn DPSK, there is no absolute carrier phase reference, instead transmitted signal itself used as phase reference. There are various applications of DPSK such as WLANs, Bluetooth and RFID communication. The most popular among them is its use of Bluetooth where π/4 - DQPSK and 8-DPSK modulation variants of DPSK has been employed.
