Method for eliminating random error of signal phase

The invention discloses a method for eliminating the random error of a signal phase. The method is based on the optimization, the estimation, the calculation and the acquisition of a real phase shift value between a start time and a key phase zero position and corrects the FFT (Fast Fourier Transfor...
