二进制绝对相移键控(2PSK)的调制和二进制相对相移键控(2DPSK)调制;从波形上是无法分辨的。如收发端采用统一的相同调制方式,即国际电信同盟ITU-T给出的2PSK和2DPSK的标准定义和传号差分码的引入。对正确识别和理解通信系统中调制波形有很大的帮助。
Binary absolute phase shift keying (2PSK) modulation and binary relative phase shift keying (2DPSK) modulation; are indefinable from the waveform. Such as the receiving end using the same uniform modulation, that is, the International Telecommunication Union ITU-T 2PSK and 2DPSK standard definition and the introduction of differential signaling. The correct identification and understanding of the modulation waveform in communication systems is of great help.
