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 1):
A phase error detection module, comprising:\n 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, 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 a phase evaluator, 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 constellation point selector comprises: an area determiner, 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; a radius comparator, 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 a constellation point identifier, generating the constellation point selection signal according to the area indication signal and the radius indication signal.
