Apparatus and Method for Correcting Phase Error

摘要

An apparatus for correcting a phase error is provided. The apparatus includes an error estimating module and a correcting module. The error estimating module receives a phase-shift keying signal, and calculates a phase error according to the phase-shift keying signal, a plurality of known candidate signals and Bayesian estimation. The correcting module corrects the phase-shift keying signal according to the phase error.
