| 摘 要： | 根据二相编码信号在相位突跳点两侧具有反相特性，提出一种二相编码解调方法：利用构造的相位突跳点样本，对各突跳点完成相关检测，并可在此基础上对编码进行重构。相关处理所具有的增益使得该方法可应用于对信噪比较低的相位编码信号的侦察。

| Abstract: | For a Binary Phase Shift Keying(BPSK) signal,the neighbouring signals on both sides of a phase jumping point are phase-reversal.Based on this property,a coherent decoding algorithm is proposed using a constructed snippet for phase jumping section with which to inspect all the phase jumping points.And then the code can be reconstructed.This method could be used in signal reconnaissance with low signal noise rate because of its coherent gain. |
