Abstract
Disclosed are a method and an apparatus for joint phase and frequency offset estimator for an MPSK transmission, in which the overall observation interval is divided into adjacent sub-intervals and a folded separate phase estimate is independently obtained from each of sub-intervals and is then unfolded to remove the discontinuity in computing phase estimate. The phase offset is then computed by averaging the unfolded phase estimates whereas the frequency offset is computed by averaging the differences between adjacent unfolded phase estimates.
