- 实验一 双极性矩形随机信号的归一化功率谱密度一 1.1 功率谱密度简介 平稳过程的任何一个非零样本函数的持续时间为无限长,显然都不满足绝对可积和总能量有限的条件。因此,它的傅里叶变换不存在即没有频谱函数。所以我们用功率谱密度来表述其频谱特性。 随机过程的任一实现是一个确定的功率型信号。而对于任意的确定功率信号f(t),它的功率谱密度为: 式中, 是f(t)的截短函数 对应的频谱函数。f(t)是平稳随机过程 的一个实现。而随机过程某一个实现的功率谱密度不能作为过程的功率谱密

K-L
- K-L变换算法 以矢量信号X的协方差矩阵Ф的归一化正交特征矢量q所构成的正交矩阵Q,来对该矢量信号X做正交变换Y=QX,则称此变换为K-L变换(K-LT或KLT),K-LT是Karhunen-Loève Transform的简称,有的文献资料也写作KLT。可见,要实现KLT,首先要从信号求出其协方差矩阵Ф,再由Ф求出正交矩阵Q。Ф的求法与自相关矩阵求法类似。-K- L
