| 摘 要： | A method for estimating frequency, amplitude and phase of a sinusoidal signal is presented based on the principle of signal matched-phase. The formulae for estimating signal parameters are derived, and the algorithm of searching for signal parameters is also given in the case where the signal frequency is unknown. The algorithm is simple and time_saving. The simulation results show that this new method is valid.
