英文: After Exploring the essential differences between noise and speech, Higher Order Statistics (HOS) are introduced in this paper and a method of using radially integrated polyspectra is applied as a feature, where multi-dimentional spectra space is transfor
中文: 在此基础上，深入分析了信号域噪声与语音的本质区别，引入了数学上的高阶累计量的思想，建立了基于高阶谱的高维杭噪特徵，利用抽向积分映射的方法将高维高阶谱空间转换为一维空间，利用非平凡谱点的非线性组合建立一维的高阶谱特徵，同时并建立基于杭噪特徵的完善的搜索算法。

英文: From the order statistics models of system failure probability as well as the form of the probability density function of order statistics itself, it can be deduced that the system failure dependence called common cause failurecan be well reflected throug
中文: 从所建立的次序统计量模型及次序统计量的概率密度函数本身的形式可以推论，共因失效这种失效相关性完全可以通过载荷分布与强度分布这两种基本参量反映出来。

英文: Since a pseudo-covariance matrix of the observed signals supply additional constraints if the sources are assumed to be independent and improper, it can be proved that the second order statistics is sufficient to separate the mixed complex-value signals f
中文: 假设源信号是独立的且非常态，信号的伪协方差矩阵能增加约束条件，从而可证明二阶统计量能够完全分离复值混合信号，而且对信号是否平稳不作要求。
