相位调制与使用ASK(幅度键控)的CW相比有很多优点。
The phase modulation has some more advantages against CW, which USES ASK (amplitude shift keying).
正如这种新操作模式的名字所指的，PSK(相移键控)调制载波的相位。
As the name of the new mode says, PSK (phase shift keying) modulates the carrier phase.
四相相移调制是利用载波的四种不同相位差来表征输入的数字信息，是四进制移相键控。
Quadrature phase shift carrier modulation is used to represent the four different phase inputs of digital information, is quaternary phase shift keying.
