• In this thesis, firstly, we put forward a new algorithm of the synchronization of carrier reference phase, that is to use the curve synthesizing with the general digital carrier phase looper to have an estimation on carrier frequency within 10 ms so as to meet the need of meteor burst communication . we have done some simulations to get the performance of carrier frequency estimation using two modulation modes ( 16qam and 4-qpsk ), and had some test on the carrier phase looper in conditions when using different baud rate transmission and when the baud tuning have windage
  我们对两种正交调制方式(16qam和4-qpsk)进行了模拟工作并给出了模拟结果，同时讨论了码元同步定时误差对锁相环路工作的影响并根据流星通信中使用变速率传输时锁相环路的载波同步性能进行了测试；然后在基于软件无线电思想的数字处理平台(该数字处理平台实现了中频数字化)上用dsp软件完成了载波的相位跟踪。
• This is by two reasons : the first, as the development of military communication technologies, it transit from digital to software implementation, intelligence, broad band implementation and network implementation . many new technologies such as adaptive frequency hopping, burst communication, broadband modulation and complex coding accelerate the research about pertinence algorithms of signal sense and signal processing . the second, three hotspots of modern signal processing-spectrum estimation, high-order statistics ( hos ) and time-frequency analysis theory become more and more consummately and being used in communication jamming and anti-jamming field
  应用于军事通信对抗的信号处理理论发展非常迅速，这得益于两个方面的动力：其一，军事通信的技术和手段不断更新，在数字化的基础上逐步走向软件化、智能化、宽带化和网络化，出现了自适应跳频、突发通信、宽带调制和复杂编码等新的实用技术，推动了具有很强针对性的信号侦测和处理领域的算法研究；其二，现代信号处理的三大热点??谱估计、高阶统计量方法、时频分析的理论和技术日臻完善，并逐渐应用于通信对抗领域。
