Abstract :
A phase correcting filtering algorithm is proposed. It utilizes cross power spectrum estimation to get the information about the signal´s frequency value and phase shift and designs a phase corrector to complete the compensation of the filtered signal´s phase and zero-phase filtering. This method has the advantages of easy implementation, high precision, good real-time performance, etc.. The results of MATLAB simulation show that the method has a reliable phase compensation performance.
