Abstract
A data storage system identifies analog-to-digital conversion samples with amplitude below a certain threshold. Remaining samples are grouped according to phase into one or more quadrants. A multi-coordinate with overlapping quadrants is used to further differentiate sample points. The system then computes an average phase for zero phase start estimation.
