Abstract:
A phase error detection module includes: a constellation point selector, generating a constellation point selection signal according to a position and a radius of data of an input signal in a constellation diagram; a symbol estimator, selecting a part of all of a plurality of constellation points in the constellation diagram according to the constellation point selection signal, as a plurality of reference constellation points for calculating an estimated symbol corresponding to the data of the input signal, and a quantity of the reference constellation points is smaller than a quantity of all of the constellation points of the constellation diagram; and a phase estimator, calculating an estimated phase error of the input signal according to the data of the input signal and the estimated symbol.

Claim (Index 4):
A phase error detection method, comprising:\n generating a constellation point selection signal according to a position and a radius of data of an input signal in a constellation diagram; selecting, according to the constellation point selection signal, a part of all of a plurality of constellation points of the constellation diagram, as a plurality of reference constellation points for calculating an estimated symbol corresponding to the data of the input signal, and a quantity of the plurality of reference constellation points is smaller than a quantity of all of the plurality of constellation points; and calculating an estimated phase error of the input signal according to the data of the input signal and the estimated symbol, wherein the constellation diagram is divided into a plurality of areas, and the step of generating the constellation point selection signal according to the position of the data of the input signal in the constellation diagram comprises: determining in which one of the plurality of areas the position of the data of the input signal is located in the constellation diagram to generate an area indication signal; determining whether the radius of the data of the input signal in the constellation diagram is greater than a radius threshold to generate a radius indication signal; and generating the constellation point selection signal according to the area indication signal and the radius indication signal.
