SVD-TLS Power Spectrum Analysis Method

The SVD-TLS (Singular Value Decomposition - Total Least Squares) power spectrum analysis method represents a commonly used approach in modern spectral estimation techniques, which can be implemented through matrix decomposition and optimization algorithms.

ARMA Modeling Algorithm for Harmonic Retrieval (SVD-TLS Based Implementation)

ARMA modeling algorithm for harmonic retrieval based on SVD-TLS (from Zhang Xianda's "Modern Signal Processing"). This algorithm remains applicable for complex harmonic signals. The program requires implementation of key functions including matrix construction, singular value decomposition, and total least squares solution.
