文章首先给出了无模糊相位重构算法，在此基础上研究了不同调制样式信号相位差分的不同特性。结果显示：相位差分序列不仅能反映出信号的调制特性，对相位编码信号而言其还包含了相位编码序列信息。文章根据研究得到的基于相位差分序列的相位编码序列恢复算法进行仿真试验，得到了较好的结果，说明了所给算法的有效性。
First of all, this paper presents a fuzzy-free phase reconstruction algorithm, on the basis of which, the different characteristics of phase difference of different modulation signals are studied. The results show that the phase difference sequence not only reflects the modulation characteristics of the signal, but also contains the phase coding sequence information for the phase coded signal. According to the phase sequence recovery algorithm based on phase difference sequence, the simulation experiment is carried out and the good results are obtained. The effectiveness of the proposed algorithm is demonstrated.
