QPSK SIMULATION Orthogonal phase shift keying (Quadrature Phase Shift Keyin, QPSK) is a digital modulation method. It is divided into two kinds: absolute phase shift and relative phase shift. As the phase ambiguity problem exists in the absolute phase shift mode, the relative phase shift mode DQPSK is used in practice.
