...It was first proposed byMcMahon and Barrett,(21) hitherto, three types of PDC methods can be described as: time shifting (TS),(22,23) window length changing(WLC),(24,25) and correction method based on asymmetrical windows (AW).(26,27) TS method needs to choose an appropriate parameter L of time delay....
