Estimating AR Model Parameters Using LD Algorithm

Resource Overview

This is my self-developed MATLAB code for estimating AR model parameters, implementing the LD (Levinson-Durbin) algorithm with comprehensive comments for better understanding. Highly recommended for learning and practical implementation!

Detailed Documentation

In the following text, I present my self-developed MATLAB code for estimating Autoregressive (AR) model parameters. This implementation utilizes the Levinson-Durbin (LD) algorithm, which efficiently computes AR parameters through recursive solutions of the Yule-Walker equations. The code includes detailed comments explaining key steps such as: autocorrelation calculation using xcorr function, recursive coefficient computation with proper indexing, and reflection coefficient derivation for stability checks. This implementation demonstrates practical numerical methods for spectral estimation and time series analysis. I believe this code is highly valuable as it not only enhances understanding of AR model fundamentals but also provides hands-on programming experience with signal processing algorithms.
