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 本文介紹了一種適合于用數(shù)字信號(hào)處理器( dsp )實(shí)現(xiàn)的全數(shù)字解調(diào)技術(shù)。該技術(shù)能方便、靈活地設(shè)計(jì)實(shí)現(xiàn)二進(jìn)制相移鍵控( bpsk )解調(diào)器,而且使用該技術(shù)可以大大降低對(duì)接收機(jī)本身的振蕩頻率精度和穩(wěn)定度的要求。
