Title: A NOTE ON PROCEDURES FOR checking persistencY of excitation
Authors: W. C. Leite Filho
Abstract: This work describes a sufficient condition for a quasi-stationary deterministic m-vector signal to be persistently exciting of order n, using the spectral density matrix estimate based on the Finite Fourier Transform FFT. It is shown that the spectral density matrix of any periodic noise-free vector signal has rank one. Moreover, it is shown that the usual assumption that the spectral density matrix should be positive definite is not applicable in this case. A procedure for checking the order of persistence is presented.
Keywords: persistent excitation, spectral density matrix, persistence checking
