Quadrature Phase Shift Keying (QPSK) is a form of Phase Shift Keying in which two bits are modulated at once, selecting one of four possible carrier phase shifts (0, 90, 180, or 270 degrees).

在带通采样条件下实现了QPSK信号的调制解调，并附有每一步的曲线图- U5728 u901A u901A u91C0 u6837 u673 u4E09 u4E0B u5B9 u3B0 u4E86QPSK u4FE1 u53F7 u7684 u8C03 u5236 u89Y3 u8E03 uFF0C u5E76 u9644 u6649 u6BCF u4E00 u6B65 U7684 u66F2 u7EBF u56FE
