摘    要:基于时域和频域两种循环谱密度估计方法,研究和总结了Frank码信号的循环谱特征及其与信号参数的对应关系。提出了一种没有先验知识条件下Frank码截获信号参数提取方法。首先介绍了Frank码信号的表示形式,给出了信号主要参数之间的关系;然后使用时域和频域两种循环谱密度函数估计方法分析了信号的循环谱特征,得到了循环谱特征与信号参数之间的对应关系;在此基础上提出了基于循环谱特征的信号参数提取方法。通过对六个Frank码信号参数提取相对误差的计算,验证了该算法的有效性。

关 键 词:Frank码  循环谱密度  参数提取

Abstract:Based on two cyclic spectral density estimating methods on time and frequency domain,the cyclic spectral features of frank coded signals are studied and the correspondence with signal parameters is investigated.A frank coded intercept signal parameter extraction method without prior knowledge is developed.Firstly,the expression of frank coded signal is described and the relationship between signal parameters is given;Secondly,the cyclic spectral features of signals are analyzed using two cyclic spectral den...
Keywords:frank coded signal  cyclic spectral density  parameter extraction
