A method is proposed for a sinusoidal signal parameters estimation, when the time-varying amplitude of the signal is the product of a known function and unknown coefficient. A new parametrization approach is applied to obtaine linear regression model. The estimation algorithm for the model and initial signal parameters is synthesyzed on the base of standart gradient method. The parameters estimation errors are shown to converge exponentialy to zero.
