Title: An adaptive zero-phase digital filter based on phase compensation
Abstract: General difference filter can not only bring phase-shifting, but also induce the wave aberration. A new zero-phase 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.
