Higher-Order Spectral Analysis Toolbox

The Higher-Order Spectral Analysis Toolbox is a comprehensive collection of M-files implementing advanced signal processing algorithms for spectral estimation, polyspectral analysis, and time-frequency distribution computations. It contains specialized functions for practical applications including time-delay estimation, harmonic retrieval, parameter estimation for Volterra (nonlinear) models, and adaptive linear prediction. The toolbox enables implementations across diverse fields such as acoustics, biomedical engineering, economics, seismic exploration, non-destructive testing, oceanography, plasma physics, radar, sonar, and speech processing through MATLAB's programming interface.
