| 摘 要： | 通过对PSK信号相位特性的分析,采用相关积累的方法充分利用单个脉冲所提供的相位跳变信息,成功提取出PSK信号相位跳变规律,在此基础上进行了相位编码序列的恢复。根据文章中研究得到的算法进行了仿真实验,仿真结果显示,算法具有良好的低信噪比环境适应能力。

| Abstract: | The problem of how to analyze PSK modulation rules is discussed. How to get the rules of phase shifting from the relative accumulation of single pulses is introduced first, and on the basis of which an approach to restoring PSK sequence is derived. The method has good adaptability under Low-SNR condition, which is proved to be right according to some simulation results. |
