相移键控

• A full - digital demodulation technique is introduced in this paper , which can make it easy and quick to design and achieve binary phase shift keying ( bpsk ) demodulator , and also can reduce the requirement of the oscillator frequency precision and the degree of stability of the receiver
  本文介绍了一种适合于用数字信号处理器( dsp )实现的全数字解调技术。该技术能方便、灵活地设计实现二进制相移键控( bpsk )解调器，而且使用该技术可以大大降低对接收机本身的振荡频率精度和稳定度的要求。
