航空航天通信技术一般采用模拟通信的频率调制和数字通信的移相键控调制方法。这有利于充分应用信道带宽和能源。频率调制是在一定程度上改变载波或副载波的频率来传输信息的调制方法。移相键控调制是利用载波或副载波的相位跳变来传输信息的调制方法。移相键控又分二相移相键控、四相移相键控和多相移相键控，其中以四相移相键控和八相移相键控调制方法的效率较高-Aerospace communications technology commonly used analog communication of frequen

在数字通信中，通常直接从接收到的数字信号中提取位同步信号，这种直接法按其提取同步信号的方式，大致可分为滤波法和锁相法。锁相法是指利用锁相环来提取位同步信号的方法，本设计方案就是基于锁相环的位同步提取方法，能够比较快速地提取位同步时钟，并且设计简单，方便修改参数。采用Quartus II设计软件对系统进行了仿真试验，并用Altera的Cyclone II系列FPGA芯片Ep2c5予以实现。-In digital communication, usually from receiving direc
