✦ Synopsis

The multiple signal classitication method (MUSIC) for spectral estimation is applied to data generated for three cases of a simple model system, based on five harmonic frequencies. The results are compared to the exact spectrum as well as to the results obtained with the Fourier transform method. The effect of the parameters required to be set in the application of the MUSIC method as well as the effect of signal-to-noise ratio on the spectral estimate and its error are studied. Spectral resolution is discussed. It is found here that MUSIC tends to yield very good estimates of the frequencies but that relative amplitudes of lines and line shapes are not generally well estimated.
