A new method of estimating the parameters of a spectrum of a finite number of sinusoids of similar amplitudes and frequencies is presented. Basically the method makes the estimation of their amplitudes and phases and try to annihilating them by the addition of sinusoids of opposite sign. The residual is used to correct the estimators.
