Differential Quadratur Phase Shift Keying

  • Differential Quaterny Phase Shift Keying
German: Differentielle Quadratur-Phasenumtastung
Japanese: 差動四位相偏移変調

Communications engineering. DQPSK is a variation of QPSK, which works with the phase change of the carrier frequency rather than the absolute phase. The signal to be transmitted is split, each tributary modulated with DPSK and both interfered with a phase shift of either ∏/2 or -∏/2. This technique results in higher data rates - up to 1 GBit/s - and is used for example with Bluetooth.
