PSELab - Power Spectrum Estimation Laboratory (PSELab)

"PSE Lab" is a freeware Windows application useful to estimate power spectrum and time frequency distribution of signals. To estimate power spectrum, the application uses following methods: periodogram; using the simplex algorithm to estimation of complex exponential model optimal parameters; using the quasi-Newton algorithm to estimation of complex exponential model optimal parameters; least squares Prony method; modified least squares Prony method; Burg method; modified covariance method; MUSIC..
