Quadrature phase shift carrier modulation is used to represent the four different phase inputs of digital information, is quaternary phase shift keying.
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。
If the "0" and "1" to change the carrier phase, called phase shift keying.
如果“0”和“1”来改变载波的相位，则称为相移键控。
There are many control strategy, such as stair waveform, carrier phase shift, voltage space vector and so on.
控制策略有阶梯波法、载波相移法和电压空间矢量法等。
Their main function is to simulate the satellite signal from the really satellite on the satellite orbit through changing code phase, Doppler shift, carrier and signal-to-noise ratio.
其主要功能就是通过改变码相位、多普勒频移、载波和信噪比来模拟卫星轨道上真实卫星发射的信号。
As the name of the new mode says, PSK (phase shift keying) modulates the carrier phase.
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。
Compared to current phase shift keying (PSK) modulation by a code, there is a further modulation by a sub-carrier.
与当前通过编码的相移键控(PSK)调制相对，还存在另外的通过子载波的调制。
The carrier phase shift technique based parallel back-to-back PWM converter is used on the direct-drive wind power system, with a switching frequency as low as 1 kHz.
直驱型风力发电系统需要全功率变流器，在现有器件功率水平以及开关频率等诸多因素制约下，变流器直接并联的方式具备结构简单、模块化设计、易扩展的优点。
