arma谱估计
输入信号为方波信号+高斯白噪声,方波信号基 频为 1kHz,幅值为 1,高斯 白噪声方差为 0.2, 均值为 0,采样频率为 20kHz。试用周期图法和 ARMA 谱估 计法(SVD-TLS)估计此信号的功率 谱,并分析比较其结果
3. ARMA 模型 (1) 平稳 ARMA 功率谱密度:
(2) 任意 ARMA:
可写为:
其功率谱:
4. Cadzow 谱估计子: (1) Cadzow 将 ARMA 功率谱分 解成两部分
(2) ni 的计算方法
5. p 阶数确定: (1) 奇异值分解:
(2) 阶数界定,v(k)小于某值(例如,0.99995):
6. A(i)的计算: (1) Sp 矩阵:
(2) A 的计算:

JTAPI是由Sun公司提出的基于Java语言的应用程序接口。由于JTAPI是基于Java的应用接口,使得JTAPI的对象独立于操作系统和硬件平台,支持跨平台的应用。JTAPI定义了一套类库,包含电话功能和扩充功能。JTAPI结合了传统的电话服务和Web处理能力,具有较强的功能。但是,基于Java的特性,使得JTAPI在拥有强大功能的同时,也失去了普及和推广的基础。-JTAPI by Sun"s Java language on the application program interface. As JTAPI is a Java-based application interface, JTAPI makes the object independent of operating systems and hardware platforms to support cross-platform applications. JTAPI definition of a set of class libraries, including telephone functions and expansion capabilities. JTAPI combination of traditional telephone services and Web processing capability, and a strong function. However, based on Java, which makes JTAPI the powerful functions, lost popularize and promote the foundation.
