Accession number: 12932091 Title: A phase correcting filter algorithm based on cross power spectrum estimation Authors: Wu Xiao-chao1 ; Cheng Ying1; Yan Liao-liao1; Zhang Ran1 Author affiliation: 1 Electron. Equip. Test Centre of China, Luoyang, China Source: Proceedings 2012 IEEE Symposium on Electrical & Electronics Engineering (EEESYM 2012) Publication date: 2012 Pages: 228-30 Language: English ISBN-13: 978-1-4673-2363-5 Document type: Conference article (CA) Conference name: 2012 IEEE Symposium on Electrical & Electronics Engineering (EEESYM 2012) Conference date: 24-27 June 2012 Conference location: Kuala Lumpur, Malaysia Publisher: IEEE Place of publication: Piscataway, NJ, USA Material Identity Number: YXB2-1901-530 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.
