Splet23. jan. 2024 · Burg法参数化功率谱估计是在Yule-Walker方程法和Levinson-Durbin快速递推法之上建立的，如果对于Yule-Walker方程法和Levinson-Durbin快速递推法不熟悉的话可 … Splet本文目标：分析AR模型并求解AR模型的输出x(n)的功率谱。 1. AR模型概念观. 数字信号处理功率谱估计方法分经典功率谱估计和现代功率谱估计，现代功率谱估计以参数模型功率谱估计为代表，参数功率谱模型如下：
SpletFunction File: [psd,f_out] = pburg(x, poles, freq, Fs, range, method, plot_type, criterion) ¶ Calculate Burg maximum-entropy power spectral density. The functions "arburg" and "ar_psd" do all the work. See "help arburg" and "help ar_psd" for further details. ARGUMENTS: All but the first two arguments are optional and may be empty. x Splet现代法谱估计（3）Burg算法MATLAB及Python实现 mat matlab python 算法 原理 前面的Yule Walker方程和Levinson Durbin算法都用到了信号的自相关序列，但是这样可能会存在自相关估计不准的问题（默认为序列长度为N，N的取值以外取不到的点都默认为0）。 而Burg是一种不需要自相关函数，直接由观测数据求解反射系数的方法，是一种与预测误 …
SpletThe Algorithm::Burg module uses the Burg method to fit an autoregressive (AR) model to the input data by minimizing (least squares) the forward and backward prediction errors while constraining the AR parameters to satisfy the Levinson-Durbin recursion. DISCLAIMER: This is work in progress!
