QPSK is one kind of two-dimensional modulating technology, the horizontal axis is called the alignment, the vertical axis is called the normal axis, corresponds separately in the star map 1 and the Q coordinate. The synchronism carrier refers to the carrier itself, the orthogonal carrier refers to the phase rotation 90 degree carrier 1 week. QPSK modulation when realization is uses the orthogonal amplitude modulation the way, some constellation in 1 coordinate s projection demodulate synchronism carrier s scope, in the Q coordinate s projection demodulate orthogonal carrier s scope, then two amplititude-modulated signal adding together is the phase-modulated wave which needs
