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:
