Differential phase shift keying (DPSK) is a common form of phase modulation that conveys data by changing the phase of the carrier wave. As mentioned for BPSK and QPSK there is an ambiguity of phase if the constellation is rotated by some effect in the communications channel through which the signal passes. This problem can be overcome by using the data to change rather than set th… dji mini pro 3 saleTīmeklisAs mentioned QPSK stands for Quadrature Phase Shift Keying. It is digital modulation technique.
