本设计采用AT89552单片机，辅以必要的模拟电路，实现了一个基于直接数字频率合成技术(DDS)的正弦谊号发生器。设计中采用DDS芯片AD9850产生频率1KHZ~10MHZ范围内正弦波，采用功放AD811控制输出电压幅度， 由单片机AT89S52控制调节步进频率1HZ。在此基础上，用模拟乘法器MC1496实现了正弦调制信号频率为1KHZ的模拟相度调制信号；用FPGA芯片产生二进制NRZ码,与AD9850结合实现相移键控PSK、幅移键控ASK、频移镇键FSK。-AT89552 the singl

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

BPSK (Binary Phase Shift Keying)，把模拟信号转换成数据值的转换方式之一，利用偏离相位的复数波浪组合来表现信息键控移相方式。BPSK使用了基准的正弦波和相位反转的波浪，使一方为0，另一方为1，从而可以同时传送接受2值(1比特)的信息。-BPSK，The conversion of analog signals into data values is one of the ways of converting the analog signals to the com
