It is found that the spectrum has the chaotic features in time domain-long range independence and aperiodicity. 通过频谱分析,发现载荷谱具有混沌信号在时域上的特征&长程不相关性及非周期性。
A Signal Index: Aperiodicity Degree Based on Matrix Singular Value Decomposition 基于矩阵奇异值分解的信号非周期性程度指标
This paper gives an effective algorithm for deciding of irreducibility and aperiodicity of nonnegative matrices. 本文为非负方阵不可约性和非周期性的判定给出了实现算法。
And several questions about the structure of the phase space of the imbedded Markov chain and its irreducibility and aperiodicity for this kind of queueing system are discussed completely, and the formula of the periodic value is also obtained. 在此基础上,完整地讨论了该系统嵌入Markov链状态空间的结构、不可约非周期性条件,并获得了周期值公式。
Chaotic system possesses some dynamic properties such as ergodicity, aperiodicity, wide-band frequency spectrum and noise-like, etc., which have been proved to be useful for secure communication. 混沌信号具有遍历性、非周期、连续宽带频谱、似噪声的特性,特别适合于保密通信等工程领域。
