The paper proposes a modification of earlier mentioned method reduces the number of computing operations and improve the accuracy of estimating the phase shift, which is close to the limit set by the Cramer-Rao inequality. The article also presents the results of numerical modeling of systematic and random errors parametric estimation of the phase shift angle of the proposed method.

Keywords: phase shift quasi-harmonic signal, Cramer-Rao lower band, parametric method
