一篇详细介绍高速数据调制解调技术，主要以QPSK信号为例，包括解调和定时，挺好的-A detailed introduction of high-speed data modem technology, mainly as an example QPSK signals, including demodulation and timing, very good

数字调制技术一套的基础功能选择特定的调制方案。一般的基础功能是互相正交的。可以使用 "克施密特正交化" 过程派生的基础功能。一旦选择了基础功能，任何信号空间中的向量可以表示为基函数的线性组合。 在正交相移键控 （QPSK） 两个正弦波 (sin 和 cos） 作为基函数调制的。调制被通过不同相的基础功能，根据消息符号。在 QPSK，调制是基础，在那里有一个符号包含 2 位的象征。
