摘要
文章研究了二相编码信号(Binary Phase Shift Keying,BPSK)盲处理结果的可信性评估问题,提出一种改进的基于相关累加曲线统计特征的处理方法。该方法在无信号先验知识的条件下,先利用处理结果建立参考信号,然后计算其与原始信号的相关累加曲线及不同可信性假设下相关累加曲线的特征差别,分别定义了相关系数及相关系数符号性特征来对BPSK信号盲处理结果的可信与否作出判断。计算机蒙特卡洛仿真证实了所提出算法的有效性。
The credibility evaluation problem is studied and a modified method based on statistical properties of the correlation curves is proposed in the paper. In the absence of a priori knowledge for the signals, the reference signal is generated by using the identification result at first. By analysis of the differences of statistical properties between the modulus of the reference signal and the observed signal under different credibility assumptions, the correlation coefficient and the signs are defined as the features to verify the credibility for the blind signal processing results for BPSK signals.Simulation results verify the effectiveness of the proposed algorithm.
