DPSK

A modulation technique in which each 1 bit triggers a phase shift of 180 degrees, but 0 bits have no effect. A number of applications specify various PSK techniques. For example,Wi-Fi5 (802.11a) wireless local area network (WLAN) standards specify binary phase shift keying (BPSK) at 6 Mbps and quaternary phase shift keying (QPSK) at 12 Mbps. See also BPSK, modulation, phase, PSK, QPSK, and WLAN.
