QPSK(Quadrature Phase Shift Keying)是一种常用的数字调制方式,它通过改变正交载波的相位来传输二进制信息。在实际通信环境中,由于发射机和接收机之间的硬件差异、环境因素等影响,接收信号往往会发生频率偏移(Frequency Offset, FO),导致解调错误。 QPSK调制将每两位二进制信息映射到四个可能的相位状态之一,其相位角为{...

The comm.CarrierSynchronizer System object compensates for carrier frequency and phase offsets in signals that use single-carrier modulation schemes.
The comm.OQPSKModulator object modulates the input signal using the offset quadrature phase shift keying (OQPSK) method and applies pulse shape filtering to the output waveform. For more information, see Pulse Shaping Filter. The output is a baseband representation of the modulated signal. For infor...
