Sinusoidal estimation methods using fourth order cumulants
M.A. Hasan · 2002
Several approaches for the estimation of the parameters of complex sinusoids corrupted with colored noise using second, or slices of fourth order cumulants are presented. Based on Toeplitz, and augmented matrix of Toeplitz matrices formed from sample cumulants, the sinusoidal frequencies are estimated using generalized MUSIC, and ESPRIT type methods.
